M5Stack Ultrasonic Distance Unit I2C | I/O (RCWL -9620)

Description:

SONIC I2C Unit is an ultrasonic distance sensor module that utilizes the I2C interface for communication. This allows for easy integration into I2C-based systems and enables the operation of multiple sensors using a single bus, optimizing I/O resource usage.

The module is equipped with an RCWL-9620 ultrasonic distance measurement chip and features a 16mm probe. The ranging accuracy of the sensor can reach from 2cm to 450cm, with an accuracy level of up to ±2%. This level of precision makes it suitable for applications that require accurate distance measurements.

By using the I2C interface, the module simplifies the integration process and eliminates the need for complex wiring. With multi-sensor operation on a single bus, it optimizes resource usage and facilitates scalability in systems that require multiple distance measurements.

SONIC I2C Unit is an ideal choice for robotics obstacle avoidance, where it can be used to detect objects within a certain range and enable navigation and path planning. Additionally, it can be employed for fluid level detection, allowing for 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.

Description:

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.
