무선 원격 검침기의 검침용 센서 IC 설계

In the paper, the design of the sensor IC used for the wireless telemetry system was discussed. The main function of the IC is to count exactly the number of the rotations of the wheel located inside the usual mechanical meter to read the magnitude of the gas, water or electric power consumption. Since the sensing system was so designed that the capacitance of the wheel varies as it rotates, the sensor IC was designed to count the number of the rotation of the wheel by continuously sensing the variation of the capacitance of the wheel. This sensing method has never been reported till now in the world.
