4.3. Physical Installation
The sensor consists of two parts: the main sensor unit and a smaller magnet. These two parts must be installed on the door/window frame and the door/window itself, respectively, with a maximum gap of 0.86 inches (2.2 cm) when closed.

Figure 4.2: Dimensions and installation steps for the sensor.
- Choose Location: Identify a clean, flat surface on your door/window frame and the corresponding moving part where the sensor and magnet can be aligned.
- Clean Surface: Ensure the installation surface is clean, dry, and free of dust or grease.
- Attach Main Unit: Peel the backing from the 3M adhesive sticker on the main sensor unit and firmly press it onto the chosen spot on the door/window frame. Alternatively, use screws for a more permanent installation.
- Attach Magnet: Peel the backing from the 3M adhesive sticker on the smaller magnet and firmly press it onto the door/window itself, aligning it with the main sensor unit. Ensure the alignment marks on both parts face each other and the gap is within 0.86 inches when the door/window is closed.
- Test: Open and close the door/window to verify that the sensor registers the change in status in the Tuya Smart Life app.
