Unit Ultrasonic
Description
Ultrasonic is an ultrasonic distance measuring sensor unit, with the capability of simultaneous reception and transmission. The ultrasonic probe has a sound frequency of 40KHz, a direction angle of ±20 ° and an accuracy of 1mm. The internal part is calculated by an RCWL-9600 ultrasonic distance measuring chip, and the measurement results can be directly obtained through I2C interface (0x57). The effective distance is 30 - 150cm.

FAQ
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.
Question: Can I use multiple ultrasonic sensors at the same time?
- Yes, you can use multiple ultrasonic sensors. Each sensor is assigned a different Trigger and Echo pin, and measured and processed separately in the code.
