Netvox Wireless Robust Metal Reed Switch Open/Close Detection Sensor - R718F-M is equipped with a Robust Metal type reed 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.

Principle of Operation

The reed switch is on (conducting) within the magnetic range, and is off (nonconducting) when it's out of the magnetic range. The module can detect the closing and opening signals so that the state of the door window status can be detected.

Example Applications

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