Abstract
A humidity sensing circuit with temperature compensation includes a wave producing module, a phase processing module, a sensing module and a detecting module. The wave producing module outputs a wave signal. The phase processing module outputs an oscillatory wave and an invert oscillatory wave according to the wave signal. The sensing module has a temperature sensor and a humidity sensor which are connected in series. The temperature sensor and the humidity sensor respectively receive the oscillatory wave and the invert oscillatory wave. The sensing module outputs a parameter signal according to the oscillatory wave and the invert oscillatory wave. The detecting module outputs a detection signal according to the parameter signal. Hence, the humidity sensing circuit with temperature compensation senses the temperature and humidity by the simple circuit design. Moreover, it is feasible for circuit design and application.
