Generating asymmetrical beam patterns approximately ±80° about the horizontal axis and 40° about the vertical, LPRS’ Pro-Wave US040015 ultrasonic sensor meets the requirements of most car reversing aids. The component has 3 wires to connect: +V power, ground and I/O digital signal. The I/O digital signal connection is a bi-directional port and provides an open collector connection with an internal pull-high resistor. The I/O port will again go low if a valid echo signal is detected after the predetermined excitation duration decided by the control pulse. The device deals with all of the analogue signals of proximity detection providing a digital output for the host system.
