PositionSense 
9-axis sensor solutions

Absolute position tracking with always-on calibration

TDK PositionSense™ is a dual-chip 9‑axis position tracking solution for instant and precise absolute heading. The PositionSense sensor solution includes the industry’s lowest power 6‑axis IMU and 3‑axis TMR-based magnetometer, with on-chip sensor fusion software and off-chip pedestrian dead reckoning (PDR) software.

Ideal for smartphones, wearables, AR/VR, drones, robotics, and more, PositionSense ensures people are never lost and are always on the right track.

CH201

Long-Range Ultra-Low-Power Integrated MEMS Ultrasonic Time‑of‑Flight Range Sensor with Millimeter Accuracy

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.
