CH101 Distance Sensor

TDK InvenSense CH101 Distance Sensor is a miniature, ultra-low power ultrasonic Time-of-Flight (ToF) range sensor based on Chirp’s patented MEMS technology. The CH101 Sensor comes in a system-in-package that integrates Piezoelectric Micromachined Ultrasonic Transducer (PMUT) with an ultra-low-power System on Chip (SoC) in a miniature, reflowable package. This fast distance sensor provides accurate range measurements to targets at distances up to 1.2m. The CH101 Distance Sensor can detect multiple objects, works in any lighting conditions, including full sunlight, and provides millimeter-accurate range measurements. This sensor features a low-power microcontroller running advanced ultrasound firmware, a dedicated programmable range interrupt pin, and a single sensor for receiving and transmitting.
