The electronic temperature sensor has a short measuring time, high measuring accuracy, easy reading, and also has a memory function. It is usually composed of temperature sensing probe, signal processing unit, display, power supply four parts. Temperature-sensitive probe is a sensitive part, generally choose one or several high-precision fast response thermistor, which is directly related to the accuracy of the output temperature and response speed; signal processing unit within the heating and prediction of two algorithms. The heating algorithm can quickly shorten the detection time; the prediction algorithm is based on the rising trend of temperature to predict the current temperature.
