Ultrasonic Distance Sensor HC SR04 Non Contact Range Finder For 3.3V Microcontrollers, Qwiic Compatible, 2 cm To 400 cm Read Range, Compact 1.75 X 0.85 Inch Board, 80 Degree Sensing, Great For DIY Projects
✔️ single unit, 3.3V I2C-ready, 2-400 cm range, 80° sensing
The compact sensor module uses the HC-SR04 ultrasonic transceiver adapted for Qwiic I2C communication, delivering non-contact distance measurements from 2 cm to 400 cm with about 3 mm accuracy. It’s designed for easy integration into hobbyist and professional robotics projects, with two Qwiic connectors for quick daisy chaining and a straightforward I2C setup. If you bypass I2C, you can tap VCC, Trigger, Echo and Ground from the edge pins. Compact, reliable, and ideal for obstacle avoidance and automation tasks.
