Overview

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

Complementing Chirp’s other ultrasonic ToF sensor products, the CH201 provides accurate range measurements to targets at distances up to 5m. Using ultrasonic pulse-echo measurements, the sensor works in any lighting conditions, including full sunlight, and provides millimeter-accurate range measurements independent of the target’s color and optical transparency. The sensor’s wide Field-of-View (FoV) enables simultaneous range measurements to multiple objects in the FoV.
