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. Now we
launch this new pyroelectric infrared motion sensor, specially designed for Arduino. It uses an integrated
digital body pyroelectric infrared sensor, has smaller size, higher reliability, lower power consumption
and simpler peripheral circuit.
