Referring to fig. 10, the detection circuit specifically includes a rectifying module, a current limiting module, an energy storage module, a voltage conversion module, and an overvoltage protection module, where the current limiting module is used to limit the energy drawn by the detection circuit from the power generation module 1, and the voltage conversion module is used to condition the voltage stored in the energy storage module to make the voltage adapt to the acceptable voltage range of the second analysis module 44; preferably, the voltage conversion module is composed of a resistor or a resistor plus a triode; the overvoltage protection module is used to protect the signal input port of the second analysis module 44 from damage.
