Low power Bluetooth beacon supports wireless sensor networking

June 27, 2014 // By Julien Happich
EM Microelectronic's COiN Bluetooth beacon is a low power solution that can be deployed anywhere iBeacon technology is used, but which also supports wireless sensor networking and many other applications over Bluetooth Smart wireless communications.

COiN consumes less than 20 µA average in a typical application, resulting in more than 18 months’ operation from a single CR2032 battery, which is included in the beacon. It also contains a built-in pushbutton switch, thus guaranteeing that your beacons have a full charge when they are deployed.

Integrated red and green LEDs provide users with feedback about the device’s operating mode. At the 0dBm output power setting, EM Microelectronic’s beacons can be detected 75 meters away by an iPhone 5S, and at maximum output power, that distance extends up to 120 meters. Circuit architecture has been optimized to be completely immune to over-the-air attacks.

COiN is shipped pre-programmed, complete with a Renata CR2032 battery and a weatherproof plastic enclosure for easy deployment, making it suitable for use at outdoor music festivals, sporting events and arenas, and anywhere a beacon is required to withstand the elements.
