  • Publication number: 20170080820
    Abstract: The invention provides a sensing circuit having a driving apparatus, that is, a current drive circuit and a voltage drive circuit. The current drive circuit drives a sensor in a current drive mode, and the voltage drive circuit drives the sensor in a voltage drive mode. The sensing circuit further has a switch apparatus connected to the driving apparatus for controlling the driving apparatus, to enable the driving apparatus to switch between the current drive mode and the voltage drive mode. A temperature testing circuit with a negative temperature coefficient thermistor is further used to sense ambient temperature of the sensor, and the input voltage of the switch apparatus is changed by means of that the resistance of the thermistor changes as the temperature changes, so as to control on and off of the switch apparatus, to switch the drive mode of the sensor.
