Ultrasonic component
This board has both an ultrasonic transmitter and receiver. The transmitter is driven by an on-board 40KHz oscillator which is enabled by the host microprocessor. The receiving sensor signal is amplified and provided as an analogue signal to be processed by a single channel ADC of the microprocessor. By measuring the time delay between enabling a transmit pulse and receiving an echo the distance of objects in a range of around 3cm to 3m can be determined.
