Description
Highlight
  • IR motion sensor to sense motion
  • Input Voltage: 4.5V – 20V
  • Delay Time: 0.5 – 200 Seconds
  • Sensing Angle: 100° Cone
  • Range 5m – 7m

PIR sensors, often referred to as, “Passive Infrared” or “IR motion” sensors, enable you to sense motion. Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits. PIR sensors are able to detect a change in average IR levels of their detection zone (e.g. when a human enters a room, that room will increase in temperature slightly) and hence sense motion.

This one’s great, as it can be powered via the Raspberry Pi’s 5V output, and be read directly from the Raspberry Pi’s GPIO input (as the sensor has a digital 3.3V output!)

This PIR includes an adjustable delay before firing (approx 0.5 – 200 seconds), has adjustable sensitivity and two M2 mounting holes! It runs on 4.5V-20V power (or 3V by bypassing the regulator with a bit of soldering) and has a digital signal output (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100 degree cone.
