Abstract: A microcomputer performs a power supply operation to a wireless communication module at a first time interval set based on a power generation amount at a lowest day power generation amount of a temperature differential power generation module. In addition, the microcomputer performs the power supply operation to a sensor at a second time interval set based on the power generation amount at the lowest day power generation amount of the temperature differential power generation module.
