SparkFun Ultrasonic Distance Sensor - TCT40 (Qwiic)

The SparkFun Qwiic Ultrasonic Distance Sensor is a user-friendly upgrade to the popular HC-SR04 sensor, offering non-contact distance measurement from 2 cm to 400 cm with an accuracy of 3 mm. Designed to seamlessly integrate with the Qwiic ecosystem for I²C communication, it simplifies adding to existing projects and daisy-chaining 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 note 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, this ultrasonic distance sensor is a versatile tool for robotics projects, obstacle avoidance systems, and any application requiring accurate distance measurement without physical contact. Its adaptability makes it a valuable addition to your toolkit.
