Small square sensor module with rotary knob and rear Grove connector

Seeed Studio

Seeed Studio Grove Rotary Angle Sensor panel mount

SKU CH-4KQ2-1W2KR

Panel-mount rotary angle sensor with 10k ohm resistance, 300 degree range and 0-5V analog output for Arduino and Raspberry Pi projects

  • Product typeSensors
  • Analog 0–5 V output for direct microcontroller reading
  • 300° linear rotation range gives predictable control
  • 10 kΩ resistance matches standard Arduino inputs
  • Grove unified socket enables plug-and-play wiring
  • Panel-mount design with rear connector fits enclosures

Panel-mount rotary angle sensor

The Seeed Studio Grove Rotary Angle Sensor is a panel-mount potentiometer that delivers an analog voltage signal proportional to shaft rotation. It connects through a Grove unified socket moved to the rear of the housing for flush mounting. The device operates at 5 V and provides a linear output across its mechanical range.

Makers needing a knob input for microcontroller

This sensor suits hobbyists and prototypers who want a simple, plug-and-play rotary control for Arduino or Raspberry Pi platforms. Builders requiring continuous rotation beyond 300 degrees, digital quadrature output, or a different resistance value should look at alternative sensor types.

300-degree linear analog output

The shaft rotates through 300 degrees with a linear change in resistance, producing a 0–5 V signal on the D1 pin of the Grove connector. The 10 kΩ track and ±20 % tolerance give predictable voltage division for direct ADC reading. The panel-mount body measures 19 mm by 19 mm by 20 mm and weighs 10 g.

Questions about this item

Does the sensor ship with any cables or mounting hardware, or do I need to buy a Grove cable separately?

The part list includes only the panel-mount rotary angle sensor itself; a Grove cable and any panel-mounting hardware are not included and must be sourced separately.

What is the angular range and resistance tolerance of this panel-mount version?

It provides a 300-degree angular range with a linear output change and a resistance tolerance of ±20% around the 10k ohm nominal value.

What voltage range will the analog output actually swing between when powered from a 5 V supply?

With a 5 V supply the output swings from 0 V to 5 V across the full 300-degree rotation, delivering a linear voltage change proportional to the shaft angle.
