TDK InvenSense MOD_CH201 Distance Sensor Module

TDK InvenSense MOD_CH201 Distance Sensor Module is designed for the CH201 distance sensor. The CH201 sensor is a miniature, ultra-low power, and long-range ultrasonic Time-of-Flight (ToF) range sensor that is based on Chirp’s patented MEMS technology. This sensor comes in a system-in-package that integrates Piezoelectric Micromachined Ultrasonic Transducer (PMUT) together with an ultra-low-power System on Chip (SoC) in a miniature, reflowable package. The sensor module board incorporates a CH201 ultrasonic sensor device with a 45° FoV acoustic housing assembly, a capacitor, and an FFC connector.
