Square-Shaped Force Sensitive Resistor (FSR) Pressure Sensor
The Square-Shaped Force Sensitive Resistor (FSR) is a lightweight, flexible pressure sensor designed to detect force, touch, squeezing, and pressure. As force is applied to the sensing surface, the sensor's resistance changes proportionally, allowing microcontrollers to measure varying pressure levels through an analog input.
Compatible with Arduino, ESP32, Raspberry Pi, NodeMCU, STM32, and other embedded platforms, this sensor is widely used in robotics, wearable technology, medical monitoring, gaming controllers, industrial automation, and interactive electronic devices.
Its square sensing area provides a larger contact surface compared to round FSR sensors, making it suitable for applications requiring more uniform pressure detection.
Whether you're designing a smart pressure pad, robotic gripper, electronic musical instrument, or human-machine interface, this sensor offers reliable and responsive force sensing for a wide range of projects.

Frequently Asked Questions
Q. Is this compatible with Arduino Uno?
Yes. The sensor works with Arduino Uno using a simple voltage divider and analog input.
Q. Can it be used with ESP32?
Yes. It is compatible with ESP32 analog input pins and other 3.3V microcontrollers.
Q. Can it measure exact weight?
No. This sensor is designed to detect relative force or pressure and is not intended as a precision weighing sensor. For accurate weight measurements, use a load cell with an HX711 amplifier.
Q. Is the sensor flexible?
Yes. The sensor is manufactured using a thin, flexible film that can be integrated into compact and curved surfaces.
Q. What applications is it suitable for?
It is commonly used in robotics, medical devices, pressure-sensitive interfaces, smart wearables, gaming controllers, automation systems, and educational electronics projects.
