Basics of IR Sensor | IR LED Pin Diagram & Working

03/11/2020· An IR sensor consists of two parts, the emitter circuit and the receiver circuit. This is collectively known as a photo-coupler or an optocoupler. The emitter is an IR LED and the detector is an IR photodiode. The IR phototdiode is sensitive to the IR light emitted by an IR LED. The photo-diode’s resistance and output voltage change in proportion to the IR light received. This is the underlying …

8 possible reasons behind AC not cooling properly - Ideas by Mr Right

29/05/2019· A compressor is the heart of an air conditioning unit which is responsible for cooling your room. If the air conditioner does not cool, the compressor might be defective. The compressor is a motor which compresses the refrigerant or coolant and circulates the refrigerant through the evaporator and condenser coils. If the compressor goes bad the cooling cycle does not start and the AC fails to cool. …

Air Conditioner Remote Controls & AC Settings: Your Ultimate …

04/03/2020· Normally a temperature sensor is located in your AC, but with a Follow-Me remote, there is also a built-in thermostat in your AC’s remote control. Once the Follow-Me mode is activated, the air conditioning unit reads the temperature of the area where the remote is located and cools/heats accordingly. This is great as the room temperature can greatly vary from one end of the room to …
