SCOPE AND PURPOSE

This document details the specification, programming and operation of an EV_MOD_CH101-03-01 (referred to as the EV_MOD_CH101

in the remainder of this document) ultrasonic sensor evaluation module. The module board incorporates a CH101 Ultrasonic Sensor

device with an omnidirectional 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.
