Overview
Force Sensitive Resistor Square 38.1mm
Measure applied pressure and force with the Force Sensitive Resistor (FSR) Square 38.1mm. This compact pressure-sensitive sensor provides a simple and convenient way to detect changes in force through a corresponding change in electrical resistance.
With a 38.1mm square sensing area, the sensor is suitable for applications where a larger contact surface is useful. It can be integrated into interactive devices, robotics, control systems, wearable electronics, smart interfaces, and experimental projects.
The FSR can be easily connected to a microcontroller such as Arduino or ESP32 using a simple voltage-divider circuit and an analog input. As the applied force increases, the sensor's resistance changes, allowing the controller to detect relative pressure levels.
Whether you're designing a pressure-sensitive button, interactive control surface, robotic sensor, or experimental force-detection system, the 38.1mm Square FSR offers a compact and practical sensing solution.

Product Technical Information
Technical Details
Force Sensitive Resistor Square 38.1mm
The Force Sensitive Resistor Square 38.1mm is a pressure-sensitive resistive sensor designed to detect changes in applied force. Its resistance varies according to the amount of pressure applied to the sensing area, allowing electronics systems to identify relative force levels.
38.1mm Square Sensing Area
The sensor features a 38.1 × 38.1mm square sensing area, providing a relatively broad surface for detecting applied pressure. This makes it useful for buttons, touch-sensitive surfaces, interactive controls, and experimental force-sensing applications.
Variable Resistance Output
An FSR does not typically provide a direct digital force measurement. Instead, its electrical resistance changes as force is applied. A microcontroller can measure this change using an analog input, typically through a voltage-divider circuit.
Arduino and ESP32 Compatibility
The sensor can be integrated with Arduino, ESP32, and other microcontroller platforms with analog inputs. This allows developers to create applications that respond to pressure or touch.
Easy Integration
The two-wire resistive design makes the FSR relatively simple to incorporate into prototype circuits. No dedicated digital communication protocol is required.
Applications
The 38.1mm Square FSR can be used for:
- Pressure-sensitive buttons
- Touch interfaces
- Robotic grippers
- Force detection
- Interactive installations
- Wearable electronics
- Smart controls
- Weight or load indication
- Arduino projects
- ESP32 projects
- Educational electronics
- DIY sensor projects
Important: An FSR is generally best suited for detecting relative changes in force rather than providing highly accurate absolute force measurements. Its response can vary with sensor construction, applied area, temperature, age, and other factors. Calibration may be required for quantitative applications.
