Mini 3-Pin Infrared PIR Motion Sensor Detector Module Body Sensor Arduino PI DIY Kit Description:This is a simple 3 pin mini passive infrared sensor that can sense movement of people, animals, or other objects. It features high sensitivity and instant reaction, commonly be used in burglar alarms and automatically-activated lighting systems. It is simple to connect in a circuit. It has 2 pins for power and gnd. One output pin that is active high. It can be interfaced with a variety of DIY boards like Pi or Arduino or similar computer boards. Features :1.Tigger : Based on infrared detection in the sensing range. Trigger output goes high.2.Delay on Trigger : Once the trigger is asserted it stays high till the delay period. On a fresh event the delay period is restarted while the trigger stays high. After the end of the delay period trigger output goes low and module is re-armed.3.Wide operating voltage range: DC4.5V-20V.4.Low power consumption : Idle current < 60 uA, especially important for battery-powered circuits.5.Output high signal is 3.3V , for easy interface to all kinds of circuits. Specifications :1. Operating Voltage Range:DC4.5-20V2. Idle current:
