How to Check AC IR Sensor on PCB: To test the IR sensor on the AC PCB, first power off the unit and access the PCB. Use a multimeter to check for voltage at the sensor terminals while pressing the remote. A reading indicates the sensor is receiving power and functioning correctly. #ACRepair #IRSensorCheck #PCBRepair #HVACMaintenance #TechTips #Troubleshooting #MultimeterUse #HomeAppliances #SensorDiagnostics #ElectronicRepair #careskillsacaemy | Care Skills Academy

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
