Overview

Chirp’s MEMS based ultrasonic technology leverages a Time-of-Flight (ToF) range sensor with a power-efficient digital signal processor (DSP) ASIC in a 3.5 mm x 3.5 mm package. The sensor handles a variety of ultrasonic signal-processing functions and algorithms, enabling customers flexible industrial design options for a broad range of use-case scenarios, including range-finding, presence and proximity sensing, object-detection and avoidance, and position-tracking.

Complementing Chirp’s miniature CH101 ultrasonic ToF sensor product, the CH201 provides accurate range measurements to targets at distances up to 5m. Using ultrasonic measurements, the sensor works in any lighting conditions, including full sunlight to complete darkness, and provides millimeter-accurate range measurements independent of the target’s color and optical transparency. The sensor’s wide Field-of-View (FoV) can be customized and enables simultaneous range measurements to multiple objects in its FoV.
