M5Stack Ultrasonic Distance Unit I/O

SONIC IO Unit is an ultrasonic range sensor module that interfaces with GPIO (General Purpose Input/Output) pins. It incorporates the RCWL-9620 ultrasonic distance measurement chip with a 16mm probe. The ranging accuracy of this sensor can reach from 2cm to 450cm, with an accuracy level of up to ±2%.

SONIC IO Unit determines the distance to a target by measuring the time lapses between transmitting and receiving pulse signals. By controlling the GPIO pins, users can directly obtain the distance value from the sensor.

The advantage of SONIC IO Unit lies in its GPIO interface, which allows for direct control and access to the distance measurement functionality. This facilitates integration and provides flexibility in incorporating the sensor into different systems or projects.

This module is well-suited for various applications that require accurate distance measurements, such as robotics obstacle avoidance and fluid level detection. In robotics, it can be utilized to detect objects within a specific range, enabling efficient navigation and obstacle avoidance. For fluid level detection, SONIC IO Unit enables non-contact measurement of liquid levels in tanks or containers.

Note: When the measurement is more than 3.5m, there will be a slight delay in the response of the distance measurement data.
