Introducing SmartSonic™Chirp Microsystems’ ultrasonic Time-of-Flight (ToF) sensors integrate a MEMS PMUT (Piezoelectric Micromachined Ultrasonic Transducer) with an ultra-low power SoC (System on Chip) in a miniature reflowable package. These sensor solutions are capable of ranging to targets of any composition up to 5m in any lighting condition make them ideal for a variety of applications including: obstacle avoidance, presence detection, robotics, security and surveillance, AR/VR, drones, liquid level sensing, smart home/building and general IoT. |
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.
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 the FoV.

Complementing Chirp’s long-range CH201 ultrasonic ToF sensor product, the CH101 provides accurate range measurements to targets at distances up to 1.2m. 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 the FoV.
