Refrigerator Air Conditioner Special Temperature Control Probe NTC10k 3435 Thermistor Temperature Sensor Temperature

Working Principle Of The In-car Temperature Sensor

The working principle of the outside temperature sensor is the same as that of the inside temperature sensor.
Sensors outside the car are generally installed in the front bumper or before the radiator, and are easily affected by the environment, so they are wrapped in an injection-molded resin case to avoid responding to sudden changes in temperature. This will enable it to accurately detect the average temperature outside the car. In addition, some models have anti-fake input circuits inside the air-conditioning computer

Input element of automatic air conditioner

①The temperature sensor inside and outside the car: It is a negative temperature coefficient thermistor sensor, used to sense the temperature inside and outside the car. When the temperature changes, the resistance changes, and the temperature signal is sent to the air-conditioning electronic control unit ECU.
②Evaporator temperature sensor: It detects the temperature of the air passing through the evaporator or the temperature change on the surface of the evaporator, and controls the coupling or disconnection of the electromagnetic clutch of the compressor. The signal is sent to the electronic control unit (ECU) to control the fan speed at low temperatures.
