NTC temperature sensor for freezer.Infrared Body Sensing Module

　　A freezer is a low-temperature refrigeration equipment commonly known as a freezer, freezer, etc., designed to achieve deep freezing effects. Freezers have various uses, ranging from the food industry to the medical industry. Depending on different usage environments and performance requirements, the refrigeration space of quick freezers ranges from -45 ℃ to 0 ℃, with independent operating temperature ranges; It is the same as the use principle of air conditioner. The refrigerator is to use a compressor to compress gaseous Freon into high-temperature and high-pressure gaseous Freon, and then send it to the condenser for heat dissipation to become normal temperature and high-pressure liquid Freon. So the condenser blows out hot air, then to the capillary tube, and into the evaporator. Since the space of Freon from the capillary tube to the evaporator suddenly increases and the pressure decreases, the liquid Freon will vaporize and become gaseous low-temperature Freon, By absorbing a large amount of heat, the evaporator will cool down and use refrigeration or air cooling to achieve cooling inside the room (box).

　　The protective cover of the freezer is equipped with an NTC temperature sensor, which enables the information processing module to process and display or warn the temperature information inside the freezer during use, ensuring the safety of items during refrigeration or freezing operations without causing any damage. At the same time, when the refrigeration or freezing temperature is reached, the information processing module controls the working state of the refrigerator to enter a constant temperature working state, reducing energy consumption.
