How To Make a Simple PIR Motion Sensor Light Using An Old AC Adapter PIR stands for "Passive Infrared." It refers to a type of technology used in motion sensors, cameras, and other devices to detect infrared radiation emitted by warm objects, such as the human body. These sensors are called "passive" because they do not emit any infrared light themselves; instead, they only detect the changes in infrared radiation within their field of view. When a warm object moves within the sensor's range, the changes in the infrared radiation pattern are detected, and the sensor can trigger an action or response based on this movement.
