Every New Year's Eve, all around the world, millions of people get together to celebrate the last minutes in a crowded square. Times Square in New York, Puerta del Sol in Madrid, Trafalgar Square in London, Piazza dil Popolo in Rome, Champs Elysees in Paris or around Sidney Opera House.
In fact, due to security reasons, authorities have to plan emergency evacuations to avoid avalanche risks. This year the city of Madrid is restricting the access to Puerta del Sol to eat the famous and typical twelve grapes to start the new year with good luck.
Previous years there were up to 7 persons per square meter and the authorities want to prevent a massive disaster. Bluetooth Connectivity Kit can help to count bluetooth devices to estimate the amount of people that are celebrating the end of the year with you. This kit features the Bluetooth module PRO for Arduino, Raspberry Pi and Intel Galileo [XBee Socket], which has been mainly designed to discover a large number of bluetooth devices in a variable area. It can be connected in an XBee shield for Arduino to work.
Take a look at the video below and our tutorials to find some interesting examples of what you can do with the Bluetooth module PRO:

Smartphone Detection via WiFi and Bluetooth Beacons
If you are looking for a professional solution you can't miss Meshlium Xtreme, Libelium's Linux router which works as the Gateway of the Waspmote Sensor Networks, and also allows to detect iPhone and Android devices and is general any device with Wifi or Bluetooth Interfaces.
These devices can be detected without the need of being connected to a specific Access Point, enabling the detection of any
smartphone, laptop or hands-free car kit device which comes into the coverage area of Meshlium.
The idea is to be able to measure the amount of people and cars which are present in a certain point at a specific time, allowing
the study of the evolution of the traffic congestion of pedestrians and vehicles.
