Overview

The DFRobot Gravity Analog Rotation Sensor is a 300° potentiometer module that turns knob position into an analog voltage signal. It is designed for Arduino and other 3.3V to 5V microcontroller projects where simple manual input is needed.

This type of sensor is useful when you want smooth, continuous control rather than an on/off switch. Common uses include adjusting LED brightness, motor speed, volume, menu values, sensor thresholds, or other analog-style inputs.

The module uses the Gravity analog interface and includes an analog sensor cable, which can make wiring easier than using a bare potentiometer. It also has a compact board layout and mounting holes for basic installation in small projects.
