  • IM21 Door Sensor

Door sensor that sends advertising when door is opened. LED flashes when the alarm is triggered.

Note that this beacon is not an iBeacon nor Eddystone beacon. The advertising data is instead wholly used for sensor data. The beacon broadcasts the MAC address and status when the door is opened, a low battery report when the battery is low and a heartbeat every 10 minutes. You will need to create an app or use a gateway to scan and get the advertising data. 

Working temperature -10C to 50C.

White only.

There is no configuration app as there is nothing to configure.
