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 × 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 5 meters. 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.
