Sonoff Door Window Sensor RF

Product Introduction

The Sonoff Door Window Sensor RF is a wireless contact sensor designed to monitor the open or closed status of doors, windows, and other entry points within a smart security system. Using 433 MHz RF wireless communication, the sensor pairs with compatible Sonoff RF bridges or RF-enabled devices to provide real-time monitoring and automation.

The sensor works by separating a magnetic contact from the transmitter when a door or window opens. This change instantly triggers a signal to the connected smart home system, allowing users to receive alerts or trigger automation scenes.

Compact and battery-powered, the device installs easily using adhesive pads and can be placed on doors, windows, cabinets, or other movable entry points. Its simple installation and reliable detection make it an effective addition to home security and automation systems.
