A PIR (Passive Infrared) sensor is a type of motion sensor that detects changes in infrared radiation within its field of view. These sensors are commonly used in security systems, lighting control, and various applications where the detection of human or animal movement is required
Passive Infrared sensors operate on a fascinating principle-detecting changes in infrared radiation within their field of view. In simpler terms, they can "see" the heat emitted by living beings and objects, making them perfect for applications like motion-activated lighting, security systems, and interactive installations.
PIR sensors are sensitive to changes in temperature, so factors like air drafts and sudden temperature changes can trigger false alarms.
They are most effective in detecting large, warm-bodied objects like humans.#Arduino PIR sensor#Motion detection #projectDIY #electronicsInfrared #motion sensor#Arduinotutorial#electronics #projectHomeautomationMotion sensing with ArduinoPIR sensor #tutorialArduino #ledlights #projectSecurity system
