Sensor Connection Checking
Transmit ultrasonic wave to the sensors, boost input signal, and detect wave.
Waveform will be found, oscillating for a certain period of time.
1. Waveform for a normal sensor connection




2. Waveform for a failed sensor connection





NOTE:
Sensor connection will be checked for oscillating period of input signal 3V. If oscillating period is more than 0.8ms, it is normal.
