NTC temperature sensor suitable for the thermostat box

　　The most critical control sites in the thermostat are temperature probes, refrigeration compressors, and hot air fans, respectively. Among them, the temperature probe uses the NTC temperature sensor probe. Its measurement end is extended in the air inside the thermostat box. It cannot be contacted with an object or box. The temperature in the box is monitored in real time. The constant temperature range, that is, set the allowable temperature upper limit and lower limit. When the probe detects the temperature below the lower limit, the hot air fan is turned on and the temperature starts to rise. When the probe detects the temperature is higher than the upper limit, the refrigeration compressor is cooling and the temperature decreases. The temperature decreases. Control back and forth.
