CH101

Ultra-low Power Integrated Ultrasonic Time-of-Flight Range Sensor

CH101 HIGHLIGHTS

APPLICATIONS

The CH101 is a miniature, ultra-low-power ultrasonic Time-of-

Flight (ToF) range sensor. Based on Chirp’s patented MEMS

technology, the CH101 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 via I²C.

FEATURES

Complementing Chirp’s long-range CH201 ultrasonic ToF

sensor product, the CH101 provides accurate range

measurements to targets at distances up to 1.2m. Using

ultrasonic measurements, the sensor works in any lighting

condition, including full sunlight to complete darkness, 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.

•

Fast, accurate range-finding

•

Operating range from 4 cm to 1.2m

Sample rate up to 100 samples/sec

1.0 mm RMS range noise at 30 cm range

Programmable modes optimized for medium

and 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.)

•

Easy to integrate

The CH101-00ABR is a Pulse-Echo product intended for range

finding and presence applications using a single sensor for

transmit and receive of ultrasonic pulses. The CH101-02ABR is

a frequency matched Pitch-Catch product intended for

applications using one sensor for transmit and a second

sensor for receiving the frequency matched ultrasonic pulse.

•

Single sensor for receive and transmit

Single 1.8V supply

I²C Fast-Mode compatible interface, data rates

up to 400 kbps

•

Dedicated programmable range interrupt pin

Platform-independent software driver enables

turnkey range-finding

•
