Heiman WS3DS Tuya WiFi smart door opening sensor
The WS3DS sensor consists of two parts: a detector and a magnet. With WiFi communication, it can detect the open or closed status 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, allowing the magnet part to be mounted on either side of the detector part, making it suitable for different types of doors.
Real-time monitoring
The Heiman WS3DS detector enables real-time monitoring of door opening and closing status. Status change information is instantly transmitted to the Tuya (Smart Life) mobile app, enhancing home security and allowing quick response in the event of an unauthorized opening.
Dual reed switches
Thanks to dual reed switches, the sensor can be installed on different types of doors. This installation flexibility makes the device versatile and easy to install, regardless of the direction of opening.
WiFi protocol and remote monitoring
The sensor uses WiFi protocol for communication, which ensures compatibility and a stable connection to the home network. This makes it possible to remotely monitor the status of the door from anywhere, giving you full control over the security of your home.
Low energy consumption
The Heiman WS3DS is designed with low energy consumption in mind. The device has a low-battery alert function that informs the user when the battery needs to be replaced. This allows the sensor to provide continuous protection.
Easy installation
Installation of the sensor is extremely easy thanks to "stick and play" technology. The device can be easily attached to the door with self-adhesive tape, eliminating the need for tools and allowing for quick and hassle-free commissioning.
Stylish design
