Adafruit Ultrasonic Distance Sensor with I2C Interface - RCWL-1601

Embrace the precision of our 3V Ultrasonic Sonar Distance Sensor with I2C Interface, perfect for a range of innovative projects from robotics to interactive art and automation. This versatile sensor operates effectively within a range of 2cm to 450cm, optimal between 10cm and 250cm, ensuring reliable distance measurement.

Designed for easy integration, it supports both 3V and 5V power with a consistent logic level, making it compatible with a variety of microcontrollers and microcomputers. The sensor communicates via I2C on a fixed 7-bit address, returning accurate distance data in um, making it a neat solution for systems lacking fast GPIO toggling or UART.

Highlighted for its simplicity, the pin layout is clearly marked: Power, SCL, SDA, and Ground. While it lacks built-in pull-up resistors, we include a pair of 10K resistors for convenient breadboard setup. Be mindful of its I2C bus specificity—it performs best alone on its bus unless multiple I2C buses are available.

Whether you're diving into CircuitPython or exploring with Arduino, this sensor stands as a cost-effective tool for creative development, backed by approachable tech support for budding innovations. For applications needing additional specifications or alternatives, explore options like the US-100 or HC-SR04 for tailored performance.
