infrared proximity sensor arduino

An IR (Infrared) sensor detects objects by emitting infrared light and measuring its reflection. When an object is nearby, the emitted IR light reflects back to the sensor’s photodiode, generating an electrical signal. This signal varies with distance, enabling applications like motion detection, proximity sensing, and obstacle avoidance in devices. #IRSensor #InfraredSensor #ProximitySensor #MotionDetection #ObstacleAvoidance #SensorTechnology #Electronics #Automation #ObjectDetection #TechInno
