TDK InvenSense CH201-00ABR

CH201 is a miniature, ultra-low power, long-range ultrasonic Time-of-Flight (ToF) range sensor. It 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 advanced ultrasonic DSP algorithms and includes an integrated microcontroller that provides digital range readings over I²C. It provides accurate range measurements to targets at distances up to 5m, works in any lighting condition, 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.
