Gravity: Analog Rotation Potentiometer Sensor for Arduino - Rotation 300°

The Gravity: Analog Rotation Potentiometer Sensor is an intuitive 300-degree rotational input module that converts manual dial positioning into a smooth analog voltage signal. Compatible with 3.3V to 5V microcontrollers like Arduino, it provides continuous parameter adjustment without the messy wiring of bare potentiometers. It is an ideal addition for students, educators, and hobbyists building interactive control panels, audio projects, and robotic systems.

Continuous 300-degree analog control

The sensor provides smooth continuous adjustment across a 300-degree rotation range, outputting a proportional voltage signal directly to your microcontroller ADC. It offers intuitive physical feedback, making it simple to dynamically adjust LED brightness, motor speeds, or sound volume.

Reliable potentiometer measurement

Using standard potentiometer principles, the module allows controllers to determine knob position accurately through voltage division. It provides a stable, easy-to-read analog input without the complex decoding software required by digital rotary encoders.

Plug-and-play Gravity interface

Equipped with a 3-pin Gravity analog connector and an included sensor cable, this board eliminates the messy wiring and soldering typical of bare components. It operates seamlessly across 3.3V to 5V logic levels for rapid, reliable classroom and prototyping setups.

Compact and easy to mount

Measuring just 22 by 31 mm, the module features integrated mounting holes for clean, stable installation into custom chassis, project boxes, or control panels. This robust footprint ensures dependable physical operation during interactive use.

Versatile project applications

This module suits diverse physical computing tasks, including smart cooling fan control, UI menu navigation, and MIDI controller dials. It is also an effective teaching tool for introducing analog electronics and sensor threshold calibration in STEM lessons.

What is included

The package includes one Gravity Analog Rotation Potentiometer Sensor module and one Gravity analog sensor cable for immediate connection.
