Ultrasonic proximity-sensing module (PSM) reference design(TIDA-060024)

This reference design is a small-form factor solution showcasing double-sided PCB spacing and minimum supporting component requirements for the PGA460 ultrasonic sensor signal conditioner. This module operates in a mono-static mode for single sensor transmit and receive operation to enable object detection through air at a range of 0.3 to 5m. Regardless of ambient temperature, humidity, and target color/transparency, object detection remains unaffected; however, maximum range can be hindered by very small or soft targets. The PGA460 operates exclusively as a slave device, and requires a separate master controller. TI recommends using the MSPEXP430F5529LP as an example master controller to repurpose the existing PGA460Q1EVM GUI and example source code.
