Product Information

Back to top

The CH101 is a miniature, ultra-low-power ultrasonic Time-ofFlight (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 I2 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.
