How to Test a PIR Sensor : 3 Steps (with Pictures ...

A PIR sensor is one that senses movement in a limited range, usually around 7 feet for cheaper sensors. The sensor "senses movement" by detecting patches of infrared radiation in front of it. Everything emits some level of infrared radiation, and the more an object emits, the more the sensor can "track" it. You rsnesor module should have two small potentiometers on it. Those potentiometers adjust the sensitivity of the sensor …

Testing a PIR | PIR Motion Sensor | Adafruit Learning System

· Testing a PIR. Now when the PIR detects motion, the output pin will go "high" to and light up the LED! Once you have the breadboard wired up, insert batteries and wait 30-60 seconds for the PIR to 'stabilize'. During that time the LED may blink a little. Wait until the LED is off and then move around in front of it, waving a hand, etc, to ...
