Keyestudio PIR Motion Sensor for Arduino - Black + Yellow
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.
