Overview

The DK-CH101 is an evaluation and development platform for the TDK InvenSense CH-101 ultrasonic Time-of-Flight (ToF) sensor. This kit includes the necessary hardware to interface the ultra-low power MEMS ultrasonic transducer with a 32-bit MCU for rapid prototyping of range-finding applications. It is designed to demonstrate high-accuracy distance measurement in a compact, low-power form factor.

Why Choose This Part

This platform allows engineers to evaluate the CH-101 sensor's ability to operate in any lighting condition, including direct sunlight, which is a major advantage over optical ToF sensors. The kit streamlines development with integrated firmware and a 32-bit processing environment capable of handling complex ultrasonic signal processing.

Applications

Robotic Obstacle Avoidance
Providing reliable distance sensing for small mobile robots and drones in various lighting conditions.
Presence Detection
Triggering wake-on-approach functionality for smart home devices and kiosks.
Liquid Level Sensing
Measuring fluid levels in tanks where non-contact ultrasonic sensing is required.
Social Distancing Monitoring
Implementing proximity alerts in wearable or stationary workplace safety devices.
