UNIT SONIC I2C is an I2C interface ultrasonic distance sensor. This allows for easy I2C integration and multi-sensor operation using a single BUS, to save I/O resources. The module features an RCWL-9620 ultrasonic distance measurement chip with a 16mm probe, which the ranging accuracy can reach 2cm-450cm(accuracy up to ±2%). It is ideal to apply in robotics obstacle avoidance, fluid level detection, and other applications that require you to perform measurements.
Note: When the measurement is more than 3.5m, there will be a slight delay in the response of the distance measurement data.

Built-in temperature compensation, reduce the temperature drift
Question: How to deal with the echo time of the ultrasonic sensor is too long or the ranging fails?
If the sensor's echo time is too long or cannot be detected, it may be because the ultrasonic sensor is too close to the obstacle, or the ultrasonic waves do not reflect properly on a particular material. You can keep the measurement target at a distance from the sensor by adjusting the operating range of the sensor.
