Sensing module

A sensing module, comprising:

• a sensing device, comprising a first reference terminal and a second reference terminal, for generating a sensing signal based on received pressure, wherein there is an equivalent impedance between the first reference terminal and the second reference terminal;
• a voltage generating device, for generating a reference voltage signal;
• a compensating device, coupled between the second reference terminal and a voltage reference terminal;
• and
• a voltage controlling device, respectively coupled to the first reference terminal, the second reference terminal, and the voltage generating device, for outputting a first voltage signal to the first reference terminal based on the reference voltage signal and a cross voltage of the compensating device;
• wherein a sensitivity of the sensing device is a first function of temperature, a value of the reference voltage signal is a second function of temperature, and the first function of temperature negatively correlates to the second function of temperature.
