Abstract: The present disclosure is aimed at correcting a frequency of a clock signal of a sensor based on a clock signal input from a microcomputer. A detection system includes a sensor and a microcomputer. The sensor is configured to be able to output sampling data generated by performing analog/digital conversion on an analog signal sampled based on a clock signal. The microcomputer generates a clock signal and outputs the clock signal to the sensor, and reads out the sampling data from the sensor. The sensor corrects the frequency of the clock signal based on the clock signal.

Abstract: A compact electronic device as a constituent element of a wireless communication system using a sensor. A first feature of the device is that a first semiconductor chip is bare-chip-mounted over a front surface of a first wiring board in the form of a chip and a second semiconductor chip is bare-chip-mounted over a second wiring board in the form of a chip. A second feature is that a wireless communication unit and a data processing unit which configure a module are separately mounted. A third feature is that the first and second wiring boards are stacked in the board thickness direction to make up the module (electronic device).
