Netvox Wireless Hall Type Open/Close Detection Sensor - R718LB is equipped with a Hall type sensor, which can be used to detect the status of the door and window. Through the built-in wireless module, it can achieve wireless alarm and other functions. It uses the SX1276 wireless communication module.

It supports a detection gap less than 3 cm for detection.

Example Applications

Doors and windows
Production line tracking
Objects to be detected open / close status
