How PIR Motion Sensors Work - The Learning Circuit

PIR or Passive Infrared sensors can detect movement by comparing variations in heat radiation of objects in their field of view. In this episode of The Learning Circuit, you can learn more about the different types, how they use lenses to increase their range, and interesting technical details about PIR sensors. Hit play to watch another great lesson from Maker Karen and be sure to check out the follow-up video where Karen shows how to use a PIR sensor in a circuit by making a motion activated snow globe: https://bit.ly/36njZAP
