[0033] The main control circuit board 2, as the "brain" of the device, is responsible for receiving signals from the vibration sensor 21 and controlling the working state of other units according to the signals. When the environment or the real object vibrates, the vibration sensor 21 (model SW-18015PZR-10G12B3) transmits the on-off signal to the main control circuit board 2. After receiving the signal, the main control circuit board 2 will immediately control other units to suspend work to protect the service life and stability of the radon gas sensor.
