1. Do not install the sensor on tile, glass, marble and other smooth and moist surfaces, so that the adhesive will not come off.
2. Do not install the sensor on the surface of high-temperature and heat objects such as lighting tubes, so that the adhesive will not come off.
3. Do not install the sensor on rough and uneven surfaces such as wall coverings, so that the adhesive will not come off.
4. Do not put the senor towards hot objects such as electrical appliances when installing to avoid false triggering caused by infrared interference.
