  • Testing our Raspberry Pi to Arduino Shields Connection Bridge with the new Raspberry Model B+September 9, 2014

    Raspberry Pi to Arduino Shields Connection Bridge is compatible with Raspberry Pi 2 Model B
    We have been testing our Raspberry Pi to Arduino shields connection bridge with the new Raspberry Pi 2 Model B to ensure its full compatibility. Check the specific article here.

    As you surely know Raspberry released his Model B+ board last July. We have been testing it with our Raspberry Pi to Arduino Shields Connection Bridge during last week, to ensure its full compatibility.

    Just in case you didn't know this product, the idea behind our bridge is to allow to use different shields, boards and modules designed for Arduino in Raspberry Pi. It allows also to connect digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.

    RaspBerry Pi B+

    We created also the arduPi library which allows to use Raspberry with the same code used in Arduino. In this library you can find conversion functions to control all the I/O interfaces in the same way as in Arduino.

    As we can see in Raspberry official website (check the link, the upper block is exactly the same as in model A/B. You may remember some changes were made in this part in the past. We are working with revision 2, as we guess the vast majority of you. Accordingly, the main change is Raspberry B+ includes more GPIO (14 pins more). See picture below.

    Raspberry Pi GPIO Pinouts

    As the former pins remains unchanged, and the GPIOs are the same, our shield connects with the board with no problems. At the end, we are very happy with the testings we have made. We have tested many of the eHealth sensors (the patient Position Sensor - Accelerometer, and the body Temperature Sensor, for example, and we do not foresee any problem for this side) and also with interruptions.

    More changes we love: the new Micro SD (the old card socket broke easy and frequently), the video onto the 3.5mm jack (one jack for audio and video), the lower power consumption and the extra USB ports.

    You can still install Raspbian - it is the default operating system, and we usually choose it. Model B+ is recommended for use in schools: it has more flexibility for learners and more USB ports than any other model.

    Our Raspberry Pi to Arduino Shields Connection Bridge works perfect with the new board (you can get the new Raspberry Model B+ board here).

    Why don't you give the Connection Bridge a try?

  • More Open Garden real project photosAugust 21, 2014

    We are very happy to show you more pics of our Open Garden projects. As you may know, Open Garden is an Open Source hardware alternative to commercial home automation to remotely control your indoor, outdoor and hydroponic plants. We strongly believe it has huge potential due to its flexibility: its made of many separate sensors and actuators - it's a very modular and flexible environment.

    As you surely remember, you can find three different Open Garden kits: indoor, outdoor and hydroponics. These kits will help you to use the solution in greenhouses or houses, external gardens or fields, or even plants in water installations, respectively.

    In the photos you can see a three node Open Garden indoor installation:

    1.- One street monitoring node - no pics, it's allocated in the balcony - which monitors temperature, humidity and external light.

    2.- A second node controlling the soil moisture of a big plant in the dining room. If you look closely at the pictures, you could appreciate the sensor: is the black wire in the left side of the Gateway, it gets into the ground on the left of the plant.

  • First complete Open Garden projects photos May 27, 2014

    We are pretty excited to show you some photos of our Open Garden projects we have taken. This project has huge potential and its appeal lies in the fact that it is made up of many separate sensors and actuators: it's a very modular and flexible project.

    As you may know, the Open Garden platform consist of three different kits: indoor, outdoor and hydroponics. These three kits will allow you to use it in houses and greenhouses, or gardens and fields, or even plants in water installations, respectively. We have tried with these kits to cover all possible growing plant scenarios.

    In the first photos (check below) you can see an Open Garden indoor installation. We are monitoring a cactus. Check in the left pic the bare soil moisture and the temperature & humidity sensors. As can be noted in the picture, the Open Garden Shield is accompanied by an XBee Shield and a Wifi module that sends data to the web application. The Open Garden Gateway is composed of the Arduino UNO board (of course), the Open Garden and XBee shields, and the Wifi module. You can see the web app in detail in the right pic. You can check the parameters measured by the sensors remotely: the app stores the information gathered in a data base and let you visualize it from an iPhone or Android device. In this case, there's no actuators implemented in the cactus.

    Indoor Open Garden installation

    In the next pair of photos you can see an Hydroponics installation and an entirely enclosured Outdoor kit. In the left pic you can see in detail the pH water sensor being allocated in the installation. If you look closely at the picture, you could appreciate the water temperature sensor: is the black wire in the right side of the Gateway, it gets into the water on the left of the box. In the right picture you can see an enclosured outdoor kit. In the left side of the shoot you can see an outdoor node. It can be fixed to the garden soil and send the data to the gateway via RF. The node also includes a solar energy supply system, and RF bidirectional communication (node - gateway) via transceivers. Note the enclosure, both gateway and nodes, prevents the entire system to be damaged by adverse environment conditions.

  • E-Health: Low Cost Sensors for Early Detection of Childhood DiseaseFebruary 20, 2014

    inspire_banner

    From Libelium, we bring you a very interesting article about early detection of pneumonia in children.

    Pneumonia is the number 1 killer of children worldwide with 2 million deaths each year. With a child dying every 20 seconds, pneumonia is a significant contributor to neonatal mortality in developing countries – more than AIDS, malaria and measles combined.

    The illness is treatable and preventable, but accurate early detection is key.

    To reduce child mortality due to Acute Respiratory Infection (ARI), the Smart Object Sensing Array invented by Guardit and licensed by Inspire Living Inc., contracted with the global NGO Project HOPE to create a device to aid in the efficient detection of tachypnea, an indication of pneumonia in children, based on Libelium’s e-Health Sensor Platform.

    Inspire Living developed an Infant Respiratory Rate Sensor device (Inspire™) from pioneering work in smart object sensing and object pattern recognition. Designed for use by community health workers who must accurately determine respiratory rates in children as part of diagnosing pneumonia, INSPIRE is an automated electronic device that satisfies UNICEF’s specifications for global products.

    An Affordable Prototyping Platform for e-Health

    Creating new healthcare applications or medical devices requires access to prototyping platforms that were once very costly to obtain, limiting development to research labs or well-funded corporations. “One of the challenges to e-Health innovation has been the lack of affordable sensors. You had to make a huge investment even before knowing if your project was viable. That is why we developed the e-Health Sensor Platform”, said Alicia Asín, CEO and co-founder of Libelium. “When you see all that can be achieved with an inexpensive prototyping platform like ours, it makes it worthwhile for makers to change things.”

    Inspire Living built the INSPIRE prototypes using Libelium’s e-Health Sensor hardware platform. “Libelium knocked it out of the ball park with their e-Health Sensor Platform Kit. With this, we had available the core of what we needed so we could add our value and focus on our solution. Libelium developed the foundation in software for us to build on; they had the hardware compatibility and conformity so that others could understand and reference our solution, and accept our design decisions more easily”, said Michael Script, co-founder of Inspire Living. “I would sum up the impact of working with using the products, services, support and forums from Libelium as game-changing.”

    ===============================================================

    After years of development and hundreds of iterations, Inspire Living, an innovations company specialized in smart object sensing with portable notification, was close to launching a new sensor system for counting breath rate for use in developing countries. They had patented a sensor and sourced a special material that could adhere to a child’s skin to keep the device in place. They had created easy-to-read icons to start the device and display the number of breaths counted; they had devised a way to manually charge the device for autonomy, for use in places where batteries and sunlight were scarce. At last ready to show the device to the world, they set out to demonstrate it to the World Health Organization (WHO), UNICEF, USAID, Project HOPE, and the Gates Foundation.

    Accuracy in breath rate testing

    In developing countries, aid workers and medical professionals use counting beads and stopwatches to test breath rate: this can lead to misdiagnosis by either under-counting or over-counting. A moving child, difficulties in remembering the count, or distractions during the count are all factors cited by UNICEF as major impediments to accurate respiratory rate counts.

    e-Health_Sensor_Kit

    e-Health Sensor Kit: a medical monitoring platform combines 10 different sensor operations

    ===============================================================

    Script, an inventor with a long career, found that Libelium had developed an e-Health sensor board integrating a number of different health tests performed on one device, available through Libelium’s DIY hardware division, on the Cooking Hacks website. The e-Health sensor platform includes a spirometer, a pulse oximeter, sensors to measure blood pressure, temperature, body position, and it can monitor a number of biometric parameters.

    e-Health_Arduino_Raspberry_Pi

    e-Health Sensor Shield over Arduino (left) and over Raspberry Pi (right)

    ===============================================================

    After receiving the e-Health Sensor Platform from Libelium, Script assembled a new system and began testing. Within days it became clear that input from more than one sensor would be needed. Script and his team started linking the other sensors’ inputs together, linking body position and heart rate to breath rate. Next, they added galvanic skin response to body position and temperature to breath rate. And, after developing various algorithms, the Inspire team found what they were looking for. They could accurately count breath rate.

    Initial Requirements: from Prototype to Clinical Trials

    The Inspire team integrated their sensor with the Libelium e-Health Sensor Platform to develop a more sophisticated diagnostic system for clinics and health professionals in developing countries. They brought the new device to a meeting in New York City of the largest NGOs. “As you would expect, most were mollified by our presentation. It was not to be believed”, said Script. After several clinical trials, visits to pediatricians and pulmonologists, more clinical research and a lot of focus “we are ready to assist health professionals deliver the breath of life”, he said.

    The INSPIRE device replaces the outdated methods used by health workers up to now. Currently, measuring breath rates involves nurses and doctors counting using a minute timer or even using beads, methods that are susceptible to errors and could cost a child the chance to receive medicine in time.

    Breath rate testing can be done on any child in any position, whether sitting or lying down

    ===============================================================

    The INSPIRE device measures patterns of breath recognition with an algorithm that analyses the data and displays the information to be easily read by non-skilled field personnel. The device tests breath rate in 15-second intervals and can conduct multiple tests within a one-minute time frame, permitting healthcare workers time to observe other signs of patient distress.

    Device evolution: from early prototype to current version

    ===============================================================

    With INSPIRE, the company has addressed many of the evolutions of the product during prototyping, and has now contracted with Project HOPE and other NGOs to take the units into the field and bring back the data they need to take the product to better developments. Clinical trials are ongoing. Results of the field trials will be available from June 2014.

  • e-Health: Monitoring Physical ReactionsDecember 16, 2013

    On the road towards constructing a Voight Kampff machine, the first stop has been the Cooking Hacks e-Health Arduino shield. This has proved a great success, and has provided us with simple and effective data collection from a number of biometric sensors.

    We have implemented the tool to report either directly to a computer via USB, or to a web server via the internet (with the addition of an ethernet shield – see below) so that data can be either processed locally, or visualized remotely.

    The sensors that we can collect data from using this equipment include:

    • Position
    • Blood Sugar
    • Temperature
    • Blood Pressure
    • Pulse
    • Oxygen in Blood
    • Airflow
    • Galvanometric Skin Response (GSR)
    • Electrocardiogram (ECG)
    • Electromyography (EMG)

    This enables us to monitor a wide variety of physiological activity relating to individuals, allowing us to attempt to profile emotional reactions from individuals. One simple implementation inflates and deflates the circles in the interface shown in the below image, visualising real-time changes in the physiology of an individual as they are exposed to different stimuli:

    Sketchy Interface

    Of most interest so far (in terms of detecting empathy) seems to be the interaction between pulse, GSR and temperature (visible attached to the board below), but only time and experimentation will tell…

  • Entrevista a Luis Martin sobre e-Health en Teknautas [El Confidencial]November 14, 2013

    "Un ingeniero aragonés fabrica un 'minihospital' con 'hardware' libre".

    La telemedicina es una tendencia al alza en los últimos años. Nada puede sustituir la entrevista entre médico y paciente en el entorno de una consulta, pero hay muchas rutinas diarias que gracias a la tecnología pueden ser más cómodas y menos intrusivas para los enfermos y suponer un menor coste para las administraciones.

    Contábamos hace poco en Teknautas que el 70% de los pacientes estaríandispuestos a ser atendidos online por su médico si la posibilidad estuviese a su alcance. Se trata sobre todo de pacientes crónicos, que sufren diabetes, cardiopatías o EPOC y que siguen un tratamiento regular y prolongado en el tiempo.

    Algo así se planteó Luis Martín, ingeniero técnico y estudiante de ingeniería industrial de Zaragoza que a sus 23 años ha quedado semifinalista del prestigioso premio internacional James Dyson con su proyecto: un minihospitalcasero, pensado para facilitar la vida de los pacientes.

    El invento, que ha desarrollado dentro de la empresa zaragozana Libelium, se llama eHealth Sensor Platform, y no es un producto final para la venta al gran público, sino un innovador kit de desarrollo lleno de posibilidades creado para que otros inventores lo utilicen, lo adapten a sus necesidades y lo mejoren.

    'Minihospitales' para zonas en vĂ­as de desarrollo

    El objetivo es crear unidades funcionales que puedan suplir en parte los costosos equipos médicos tanto en el día a día de los pacientes de países occidentales como en zonas en vías de desarrollo. “Puede servir como unminihospital en lugares donde no hay nada”, explica Martín.

    De momento, eHealth Sensor Platform es capaz de monitorizar diez parámetros vitales: la temperatura corporal, la posición del cuerpo, la glucosa en sangre, la tensión arterial, la actividad cardiaca, la sudoración, la oxigenación de la sangre, el pulso, el ritmo respiratorio y los impulsos musculares.
