The other end of R1 is connected with one end of thermistor R2 and has node, test side of the node as temperature detecting unit 102
Ground terminal 104 of the other end of 105, thermistor R2 as temperature detecting unit 102, with reference GND is connected.
Specifically, thermistor R2 can be put into the position for needing to detect temperature, and the resistance value of thermistor R2 can be according to temperature
Degree changes and changes.As a result, when detecting the temperature change of position, the change in resistance of thermistor R2, the voltage hair at node
Changing, detection chip 103 can determine the temperature of detection position according to the voltage at node, realize temperature detection.
It should be noted that thermistor R2 can be with NTC (Negative Temperature Coefficient
