- The Zio Ultrasonic Distance Sensor is great, both precise and fast
- It provides a wider detecting angle than other models
- It can also be used like any other HC SR04 board
The Zio Ultrasonic Distance Sensor may look familiar it is indeed the HC SR04! We have incorporated this sensor into our Qwiic family, as it provides a wider detecting angle and greater distance than the TOF sensor. You dont need to worry about the inner details or VCC, Trig, Echo and GND pins; simply treat it as another I2C device and set it up with ease. If you are curious, however, you can check out the STM8 code used to transfer the data over I2C.
Furthermore, this board can be used both with a Qwiic connector and with a pin header, which is provided. For more information on how the Ultrasonic sensor works, you can check out this page!
Note: Avoid touching the pins and pads on the backside, as the sensor measurement is based on analog single; doing so may make the result unstable.
