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. 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. Input Voltage: 3.3 ~ 5V, 6V Maximum Working Current: 15uA Working Temperature: -20 ~ 85 ℃ Output Voltage: High 3V, low 0V Output Delay Time (High Level): About 2.3 to 3 Seconds Detection angle: 100 ° Detection distance: 7 meters Output Indicator LED (When output HIGH, it will be ON) Pin limit current: 100mA
