Generic RFP Thin Film Pressure Sensor Resistance/Voltage Conversion Module for FSR4 Series
The RFP Thin Film Pressure Sensor Resistance/Voltage Conversion Module is a dedicated signal conditioning circuit designed to interface FSR4 series resistive sensors with 3.3V or 5V microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi. It converts the sensor’s variable resistance into a linear analog voltage (0-5V) and provides a digital threshold output for simplified pressure detection.
Features
- Converts FSR4 sensor resistance to 0-5V analog voltage (AO) and digital threshold (DO) output.
- Wide 3.3V to 5V DC operating range for compatibility with Arduino, ESP32, STM32, and Raspberry Pi.
- Compact PCB footprint (14mm x 32mm) for easy integration into wearable, robotics, and embedded projects.
- Simple 4-pin interface (VCC, GND, AO, DO) for plug-and-play connectivity.
- Provides simultaneous analog and digital outputs for flexible system design.

This signal conditioning module serves as a dedicated interface for FSR4 series thin-film force-sensitive resistor (FSR) sensors. It employs a precision voltage divider and comparator circuit to translate the sensor’s pressure-dependent resistance into a clean, linear analog voltage signal proportional to the applied force. The digital output provides a clean, debounced logic signal that toggles when the analog signal crosses a preset threshold, set by an onboard potentiometer.
Engineered for robust performance in embedded systems, the module operates across a 3.3V to 5V DC range, making it directly compatible with a vast array of development boards and microcontrollers without requiring external level shifters. Its compact, solder-masked PCB is designed for reliable operation in applications ranging from prototype breadboarding to final product integration.
