An accelerometer system includes a magnet having a first end and a second end opposite the first end. The magnet is configured to generate a magnetic flux that flows through the magnet from the second end of the magnet to the first end of the magnet a proof mass extending through the magnet. The accelerometer system also includes a first coil disposed around a first portion of the magnet, a second coil disposed around a second portion of the magnet, and processing circuitry. The processing circuitry is configured to receive a signal corresponding to a capacitance of an interface between the magnet and the proof mass, cause a first current to flow through the first coil, and cause a second current to flow through the second coil. A first Lorentz force and a second Lorentz force maintain the proof mass in a null position.

The sensor module includes a sensor that detects environmental information of an object equipped with the sensor module, a resonator, an integrated circuit device, and a package that houses the sensor, the resonator, and the integrated circuit device. An integrated circuit device includes an oscillation circuit configured to generate a clock signal using a resonator, a real-time clock circuit configured to generate time information based on the clock signal, and a processing circuit configured to output, as log information, output environmental information based on an output signal of a sensor in association with the time information from the real-time clock circuit.
