USSM Arduino Library

The compact TDK Ultrasonic Sensor Module measures distances completely invisibly and contact-free. It detects objects using inaudible ultrasonic waves transmitted and received by a piezoelectric disc. 

Customers can evaluate the Ultrasonic Sensor Module using an Arduino Uno microcontroller board. Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into various electronic projects.

The TDK USSM Arduino library implements the sensor’s proprietary communication interface, providing easy access to the sensor’s functions. The following application note describes a simple hardware setup and an example Arduino sketch that periodically issues “SEND A” commands and reports the measured range in cm.
