TDK extends ultrasonic ToF sensor platform for long-range up to 5m

TDK has made global availability of its new Chirp CH201 long-range ultra-low power integrated ultrasonic Time-of-Flight (ToF) range sensor platform. CH201 MEMS sensor, sensor modules, and developer kits along with Chirp original CH101 ultrasonic ToF sensor product is offered as a solution. CH101 is for short range cases up to 1.2m, and the new CH201 provides exact long-range measurements to targets at distances up to 5m. Chirp's MEMS ultrasonic technologies uses proprietary Time-of-Flight (ToF) range sensors in a 3.5 mm x 3.5 mm package having MEMS ultrasonic transducer with a power-efficient digital signal processor (DSP) on a low-power mixed-signal ASIC.

Both CH101 CH201 are compact and designed for ultra-low power consumption and works in any lighting condition, including full sunlight to complete darkness independent of the target's color and optical transparency. Both have a configurable Field-of-View (FoV) and a flexible DSP capable of handling a variety of ultrasonic signal-processing algorithms.

Applications suggested include range-finding, presence/proximity sensing, and object-detection/avoidance.

Chirp provides a complete sensor API and reference design to make it easy for solution providers to quickly incorporate ultrasonic range-finding technology into their tracking solutions. The complete hardware and software reference design combines Chirp ultrasonic solutions along with a BLE-enabled MCU, for a complete social distancing solution including contact tracing.
