Installation Precautions:
 
​Choose a suitable installation location away from air conditioners, curtains, fans, plants, etc. to avoid interference.​
Avoid direct beam irradiation on the ground, walls or doors to minimize reflections and indirect detections.​
Configure appropriate detection distance, sensitivity and delay time to reduce interference from objects.​
Keep the sensor surface clean and free from dust and obstacles.​
Ensure the sensor has enough space around it for proper air circulation.
