Magnetic Contact Sensor | 433MHz, Window or Door | Tuya Smart Life

The Magnetic Contact Sensor is a 433MHz radio frequency fundamental component in wireless home security and automation systems. It is primarily used to monitor the open or closed status of doors, windows, gates, or drawers.

Unlike WiFi sensors that connect directly to a router, these devices operate on the 433MHz radio frequency, which offers excellent range and battery efficiency but typically requires an RF bridge or a compatible alarm panel to communicate with a smartphone app.

Product features

• Wireless protocols: the device uses 433MHz radio frequency to operate.
• LED indicators: small lights on the unit usually flash to indicate successful pairing, low battery, or a triggered state.
• Instant notifications: when the magnet is removed, the user will get an alert that the door or window is open or closed.
