The MOD_CH101-03-02 is a miniature, ultra-low-power ultrasonic Time-of-Flight (ToF) range sensor module with a particle ingress filter and an acoustic housing providing a 45° field-of-view. Based on Chirp’s patented MEMS technology, the MOD_CH101-03-02 is a system-in-package device that integrates a PMUT (piezoelectric micromachined ultrasonic transducer) together with an ultra-low-power SoC (system on chip) mounted on a small PCB. The SoC runs Chirp’s advanced ultrasonic DSP algorithms and includes an integrated microcontroller that provides digital range readings via I²C.
