CH101-00ABR

CH101-00ABR is a miniature, ultra-low power integrated ultrasonic time-of-flight range sensor. Based on Chirp’s patented MEMS technology, it is a system-in-package that integrates a PMUT together with an ultra-low-power SoC in a miniature, reflowable package. The SoC runs Chirp’s advanced ultrasonic DSP algorithms and includes an integrated microcontroller that provides digital range readings via I²C. CH101 provides accurate range measurements to targets at distances up to 1.2m. Using ultrasonic measurements, the sensor works in any lighting condition, including full sunlight to complete darkness, and provides millimetre-accurate range measurements independent of the target’s colour and optical transparency. Application includes augmented and virtual reality, robotics, obstacle avoidance, mobile and computing devices, proximity/presence sensing, ultra-low power remote presence-sensing nodes, home/building automation.
