Wireless open / close sensor detects and logs in its memory events of door opening and closing. If a change of state is detected, the device immediately sends the notification to Efento Cloud or other IoT cloud platform. The device uses magnetic sensor to detect open / close event.

Efento sensors transmit the data over cellular network (Narrowband IoT and LTE-M) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT / LTE-M sensors can be integrated with any cloud platform.
