CH101
Ultra-low Power Integrated Ultrasonic Time-of-Flight Range Sensor
CH101 HIGHLIGHTS
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 I
2
C.
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.
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.
