MerryIoT Open/Close
(Door Window Sensor)

Reference Manual
DW10-915
DW10-868

Model Name: DW10
BQW_02_0034.005

Description

The MerryIoT Open/Close sensor utilizes LoRaWAN connectivity to communicate the proximity or not of a magnet. The intended use is to place the sensor and magnet on separate elements of a door or window to determine if the door or window is open or closed. The sensor is composed of two parts. The main body contains active electronics to measure magnetic fields and transmit any changes to a LoRaWAN network. The second part is a permanent magnet of sufficient field strength to be detected by the Hall Effect sensor on the main body.
There are also vibration and tilt detection in case of tampering.
Once the event is detected, the sensor will send an uplink and keep a buzzer alarm (Optional).
