CH201-00ABR

CH201-00ABR is a miniature, ultra-low power ultrasonic time-of-flight range sensor. Based on Chirp’s patented MEMS technology, the CH201 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 over I²C. CH201 provides accurate range measurements to targets at distances up to 5m. Based on ultrasonic pulse-echo measurements, the sensor works in any lighting condition, including full sunlight, and provides millimetre-accurate range measurements independent of the target’s colour and optical transparency. Application includes user presence in home/building automation and personal electronics, obstacle avoidance, robotics and drones, ultra-low power remote presence-sensing nodes, augmented/virtual reality and gaming, gesture control, liquid level sensing & shelf inventory monitoring.
