CH-101
GENERAL INFORMATION
The CH-101 is a miniature, ultra-low-power ultrasonic Time-of-
Flight (ToF) range sensor. Based on Chirp’s patented MEMS
technology, the CH-101 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.
Complementing Chirp’s other ultrasonic ToF sensor products,
the CH-101 provides accurate range measurements to targets
at distances up to 1.2 m. Using ultrasonic pulse-echo
measurements, the sensor works in any lighting conditions,
including full sunlight, and provides millimeter-accurate range
measurements independent of the target’s color and optical
transparency. The sensor’s wide Field-of-View (FoV) enables
simultaneous range measurements to multiple objects in the
FoV.
