Bluetooth LE passive infrared motion sensor beacon for sensing and IoT applications. Used for sensing there's a person/animal or something warm moving up to 5m away (See the IR model for detection <50cm). The beacon advertises when there's a change of state from 0->1 or 1->0 or every advertising interval if there's no change of state.

Can power from 2x CR2032 or via micro USB smartphone charger (not supplied). Slide switch on bottom selects between battery and micro USB power.

Note that this Bluetooth beacon is not an iBeacon nor Eddystone beacon. The advertising data is instead wholly used for sensor data. The beacon broadcasts data with the status and sensor data. You will need an app or gateway to scan and get the advertising data. 

3.5 years battery life with default advertising interval and 120 events per day.

Black only.

An Android configuration app allows changing of transmit power level and the advertising interval (100ms to 10 mins, default 10s). There is no iOS configuration app.

Supplied with details how to access technical and programming information.
