An IR (infrared) sensor detects objects by emitting infrared light and sensing its reflection from an object. When the object is near, the reflected light is detected by the sensor's receiver. This signal is then converted into an electrical output, commonly used in proximity detection and object recognition systems. #IRSensor #InfraredTechnology #ObjectDetection #ProximitySensor #SensorTechnology #DistanceMeasurement #IRLight #ElectronicsComponents #AutomationTools #SensingDevice #careskillsaca
