Description

The HS-S28-L module integrates a rotary potentiometer onto a small PCB, functioning as a precise analog position sensor. As the shaft rotates, the internal wiper moves across a resistive track, producing a linear analog voltage output on the signal pin that is directly proportional to the angular position. This output requires an external ADC (Analog-to-Digital Converter), commonly found on microcontrollers, for digital interpretation.

Designed for embedded control systems, the module operates from a single 3.3V to 5.5V DC supply, making it directly compatible with 5V Arduino boards and 3.3V platforms like ESP32 and Raspberry Pi GPIO. The inclusion of a standard PH2.0 3-pin connector simplifies wiring and prototyping, while the PCB’s mounting holes ensure mechanical stability in final assemblies such as robotic joints, user interface dials, and feedback mechanisms.

Key Features

  • Precision Analog Sensing: Delivers a smooth, continuous voltage output for high-fidelity angular position feedback.

Frequently Asked Questions

What is the output signal of the HS-S28-L module?

The HS-S28-L provides a pure analog voltage output on its signal pin. The voltage varies linearly from 0V (or a minimum value) up to the supplied VCC voltage (3.3V or 5V) as the knob is rotated through its full 300-degree mechanical range. This signal must be connected to an ADC input pin on a microcontroller like an Arduino or ESP32 for digital reading.

How do I wire and power this potentiometer module?

Connect the module's PH2.0 3-pin connector: the 'V' pin to your system's 3.3V or 5V power rail, the 'G' pin to ground, and the 'S' (signal) pin to an analog input pin on your microcontroller (e.g., A0 on Arduino). Ensure your power supply is within the 3.3V to 5.5V DC range. No external pull-up resistors are required for basic operation.

Can I use this sensor with a 3.3V microcontroller like an ESP32?

Yes, the HS-S28-L is fully compatible with 3.3V logic systems. You can power it directly from the ESP32's 3.3V pin. The analog output voltage will then scale from 0V to approximately 3.3V, which is perfectly within the safe input range for the ESP32's ADC pins, providing full resolution for your angle measurements.

What is the mechanical rotation range and lifespan?

This potentiometer provides a standard 300-degree mechanical rotation. It is built with a metal shaft and carbon film resistive element designed for repeated manual adjustment, typical of consumer-grade rotary encoders. While not rated for infinite industrial cycles, it is durable for prototyping, educational use, and low-duty-cycle control interfaces.
