Counting device

Abstract

The present disclosure provides a counting device capable of accurate counting even when sufficient power generation is not performed in a power generation device.SOLUTION: A counting device comprising: a power generation device that uses a change in a magnetic field; a magnetic sensor that detects the change in the magnetic field; a magnet that generates the change in the magnetic field; a processing circuit that performs counting based on the change in the magnetic field; a storage circuit that records a count value counted by the processing circuit; and a determination circuit that has at least two thresholds including a predetermined first threshold and a second threshold smaller than the first threshold and determines a voltage level of a generated voltage generated by the power generation device based on the thresholds, wherein the processing circuit performs processing in accordance with the voltage level.SELECTED DRAWING: Figure 7
