Supercooling or Overheating Circuit Breaking Protection by Temperature Sensor

Temperature sensor means able to feel the temperature sensor and converted into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument and has a wide variety. According to the measurement method, it can be divided into two types: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into two types: thermal resistance and thermocouple.

Comparing two or more data items to determine if they are equal, or determining the size relationship and ordering between them is called comparison.
A circuit or device capable of implementing such a comparison function is called a comparator. A comparator is a circuit that compares an analog voltage signal to a reference voltage. The two inputs of the comparator are analog signals, and the output is binary signal 0 or 1. When the difference of the input voltage increases or decreases and the positive and negative signs remain unchanged, the output remains constant.
