The TCT40 distance sensor is excellent for non-contact distance readings from 2cm to 400cm. This unit features a pair of Qwiic connectors, allowing you to utilize I2C.
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 easy 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, which are broken out on the board's edge. Please note that this ultrasonic sensor arrives uncalibrated, and you will need to adjust 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.
