The Sonoff DW2 Wireless Sensor utilizes a magnetic reed switch principle, where physical separation of the sensor body from its paired magnet closes the circuit, triggering a 433MHz RF transmission. This signal is received by a compatible Sonoff hub or bridge, which then pushes an alert to the user’s smartphone via the eWeLink cloud service.
Engineered for reliability in residential environments, it operates within a -10°C to 40°C temperature range. Its primary function is to monitor the open/closed status of doors, windows, cabinets, or any entry point, enabling security alerts and triggering smart home scenes such as turning on lights.
