Libelium's LoRa module works in both 868 and 900 MHz ISM bands, which makes it suitable for virtually any country. Those frequency bands are lower than the popular 2.4 GHz band, so path loss attenuation is better in LoRa. In addition, 868 and 900 MHz are bands with much fewer interference than the highly populated 2.4 GHz band.

Besides, these low frequencies provide great penetration in possible materials (brick walls, trees, concrete), so these bands get less loss in the presence of obstacles than higher bands.

The usage of the Radiation Sensor Board board along with the affordable and easy to use Arduino platform helps people to get radiation values from specific places.

The radiation board has two main parts, the power circuit and the signal circuit.

Modbus allows communication between many devices connected to the same network, for example a system that measures temperature and humidity and communicates the results to a computer

Many of the data types are named from its use in driving relays: a single-bit physical output is called a coil, and a single-bit physical input is called a discrete input or a contact.

The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi.

It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.

RFID (Radio Frequency Identification) is a technology that uses electromagnetic fields to identify objects in a contactless way; it is also called proximity identification.

There are 2 elements in RFID communications: the RFID module (or reader/writer device) and an RFID card (or tag). The RFID module acts as the master and the card acts as the slave; this means the module queries the card and sends instructions to it. In a normal RFID communication, the RFID module is fixed and the user takes his card near it when he needs to start the interaction.

CAN is a multi-master broadcast serial bus standard for connecting electronic control units (ECUs). Each node is able to send and receive messages, but not simultaneously. A message consists primarily of an ID (identifier), which represents the priority of the message. A CAN message that is transmitted with highest priority will succeed and the node transmitting the lower priority message will sense this and back off and wait.

The information is transmitted by two twisted wires that connect all system modules. It is transmitted by voltage difference between the two levels. The high voltage value represents 1 and low 0. Its combination forms an appropriate message.

The 4-20 mA Current Loop Board is one of the most robust sensor signaling standard. Current loops are ideal for data transmission because of their inherent insensitivity to electrical noise. In a 4-20 mA current loop, all the signaling current flows through all components; the same current flows even if the wire terminations are less than perfect.

All the components in the loop drop voltage due to the signaling current flowing through them. The signaling current is not affected by these voltage drops as long as the power supply voltage is greater than the sum of the voltage drops around the loop at the maximum signaling current of 20 mA.

Moreover, Libelium has developed a specific API to allow using this module with Waspmote. There are many useful functions which can be used as a guideline for other designs.

The RS-232 standard was first introduced in 1962 by the Radio Sector of the EIA. The original DTEs (data terminal equipment) were electromechanical teletypewriters, and the original DCEs (data circuit-terminating equipment) were usually modems.

For many years, an RS-232-compatible port was a standard feature for serial communications, such as modem connections, on many computers. The RS-232 standard is still used to connect industrial equipment (such as PLCs), console ports and special purpose equipment.

If you are interested in Internet of Things (IoT) or M2M projects check our open source sensor platform Waspmote which counts with more than 100 sensors available to use 'off the shelf', a complete API with hundreds of ready to use codes and a low consumption mode of just 0.7µA to ensure years of battery life.
