Introduction:
The Pyroelectric infrared motion sensor can detect infrared signals from a moving person or moving animal, and output switching signals. It can be applied to a variety of occasions to detect the movement of human body. Conventional pyroelectric infrared sensors require body pyroelectric infrared detector, professional chip, complex peripheral circuit, so the size is bigger, with complex circuit, and lower reliability.
Note
1. The maximum distance is 3-4 meters during testing.
2. When testing, first open the white lens, you can see the rectangular sensing part. When the long line of the rectangular sensing part is parallel to the ground, the distance is the best.
3. When testing, the sensor needs to be covered with white lens, otherwise it will affect the distance.
4. The distance is best at 25?, and the detection distance is shortened when it exceeds 30?.
5. Done powering up and uploading the code, you need to wait 5-10 seconds then start testing, otherwise it is not sensitive.
