CH201

Long-Range Ultrasonic Time-of-Flight Range Sensor

CH201 HIGHLIGHTS

FEATURES

CH201 is a miniature, ultra-low power, long-range ultrasonic

Time-of-Flight (ToF) range sensor. Based on Chirp’s patented

MEMS technology, the CH201 is a system-in-package that

integrates a PMUT (Piezoelectric Micromachined Ultrasonic

Transducer) together with an ultra-low power SoC (System on

Chip) in a miniature, reflowable package. The SoC runs Chirp’s

advanced ultrasonic DSP algorithms and includes an integrated

microcontroller that provides digital range readings over I²C.

•

Fast, accurate range-finding

•

Operating range from 20 cm to 5m

Programmable modes optimized for long or

short-range sensing applications

•

Customizable field of view (FoV) up to 180°

Multi-object detection

Works in any lighting condition, including full

sunlight to complete darkness

•

Insensitive to object color, detects optically

transparent surfaces (glass, clear plastics etc.)

Complementing Chirp’s CH101 ultrasonic ToF sensor product,

CH201 provides accurate range measurements to targets at

distances up to 5m. Based on ultrasonic pulse-echo

measurements, the sensor works in any lighting condition,

including full sunlight, and provides millimeter-accurate range

measurements independent of the target’s color and optical

transparency. The sensor’s Field-Of-View (FOV) can be

customized and enables simultaneous range measurements to

multiple objects in the FOV. Many algorithms can further

process the range information for a variety of usage cases in a

wide range of applications.
