The SparkFun Qwiic Ultrasonic Distance Sensor, a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm. This sensor is designed to seamlessly integrate with the Qwiic ecosystem for I2C communication, making it a breeze to add to your existing projects and daisy-chain with other Qwiic components.

If you prefer to bypass the Qwiic connector and I2C, you can also access the VCC, Trigger, Echo, and Ground pins broken out on the board's edge. Please be aware that this ultrasonic sensor comes uncalibrated, and you will need to manipulate the raw output for your specific application.

With its wide range of applications, the SparkFun Qwiic Ultrasonic Distance Sensor is a versatile tool for robotics projects, obstacle avoidance systems, and any application that requires accurate distance measurement without physical contact. Its adaptability makes it a valuable addition to your toolkit.

Jargon buster

Plain-language definitions for the technical terms used above.

I2C: I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
Qwiic: Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
VCC: VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
