Product Overview
The CH201 is a miniature, ultra-low power, long-range ultrasonic Time-of-Flight (ToF) range sensor from Chirp Microsystems. Leveraging Chirp's patented MEMS technology, it integrates a PMUT and an ultra-low power SoC in a reflowable package. This system-in-package provides digital range readings up to 5 meters with millimeter accuracy, operating independently of lighting conditions, target color, and optical transparency. Its customizable Field-Of-View (FOV) allows for simultaneous measurements to multiple objects, making it suitable for a wide range of applications including user presence detection, obstacle avoidance, robotics, and AR/VR.
