This document details the specification, programming, and operation of an EV_MOD_CH101-01-02 (also referred to as the EV_MOD_CH101 in this document) ultrasonic sensor evaluation module. The module board incorporates a CH101 Ultrasonic Sensor device with an 45° field-of-view acoustic housing assembly, a capacitor and an FPC/FFC connector. This evaluation module can perform pitch-catch and pulse-echo range-finding at distances from 4 cm to 1.2m. Several programming options are available for medium and short-range applications.
