PB-000073 CH-101 Product Brief GENERAL INFORMATION APPLICATIONS        The CH-101 is a miniature, ultra-low power ultrasonic Time-ofFlight (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. Based on 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.
