DESCRIPTION

· CH201 is a miniature, ultra-low power, long-range ultrasonic Time-of-Flight (ToF) range sensor.

· It integrates a PMUT and an ultra-low power SoC in a reflowable package.

· The SoC runs advanced ultrasonic DSP algorithms and includes an integrated microcontroller.

· Provides digital range readings over I2C with a range up to 5m.

· Works in any lighting condition and provides millimeter-accurate range measurements.

· Field-Of-View (FOV) can be customized for simultaneous range measurements to multiple objects.

FEATURES

· Fast, accurate range-finding from 20 cm to 5m.

· Programmable modes for long or short-range sensing.

· Customizable FoV up to 180° with multi-object detection.

· Insensitive to object color and detects optically transparent surfaces.

· Single 1.8V supply with I2C Fast Mode compatible interface.

· Dedicated programmable range interrupt pin.

· Miniature 3.5mm x 3.5mm x 1.26mm, 8-pin LGA package.

· Low-power SoC with operating temperature range of -40°C to 85°C.

APPLICATIONS

· User presence in Home/Building Automation and Personal Electronics.

· Obstacle avoidance in Robotics and Drones.

· Ultra-low power remote presence-sensing nodes.

· Augmented/Virtual Reality and Gaming.

· Gesture control and Liquid level sensing.

· Shelf inventory monitoring.
