A Complete Guide to Motion Sensors: What You Need to Know

WebPIR (passive infrared) sensors measure infrared (IR) light radiating from moving objects that emit heat. The sensor allows you to detect motion of people, animals and cars to trigger security alarms and lighting. They are often used in PIR-based motion detectors. PIR sensors are passive due to the fact that no heat or energy is emitted by the ... WebUsing the PIR sensor is simple: power it up, connect a pull-up resistor to the open-collector signal pin, and watch for it to go low. The PIR can sense abrupt changes in scenery as far as 10 feet (~3m) away. Once your microcontroller is sensing movement, it can trigger a buzzer, text message, tweet, or a klaxon.
