Heiman WS3DS Tuya WiFi Smart Door Opening Sensor

The WS3DS sensor consists of two parts: a detector and a magnet. Using WiFi communication, it can detect the open or closed state between the door frame and the door, sending information about the status change to the application in real-time. Dual reed switches provide installation flexibility, as the magnet part can be mounted on either side of the detector part, making it suitable for various types of doors.
