Force Sensor Resistor Square 38.1mm

This is a force-sensitive resistor (FSR) with a square sensing area of 1.75 x 1.5 inches. The resistance of this FSR varies based on the applied force: the harder the force, the lower the resistance. When no force is applied, the resistance is greater than 1MΩ.

The Force Sensor Resistor Square 38.1mm can detect forces ranging from 100g to 10kg. It has two pins extending from the bottom with a 0.1-inch pitch, making it compatible with breadboards. The sensor features a peel-and-stick rubber backing for easy mounting.

To use this FSR, connect a resistor to form a voltage divider and measure the voltage at the junction to determine the applied force. While these sensors are easy to set up and effective for detecting force, they are not highly precise. They are suitable for applications where you need to sense squeezing or pressing, but not for precise measurements like weighing scales.

Specifications:

• Dimensions:
  • Overall length: 3.5 inches
  • Overall width: 1.75 inches
  • Sensing area: 1.75 x 1.5 inches

Features:

• Force Range: 100g to 10kg
• Resistance Range: >1MΩ when no force is applied
• Pin Pitch: 0.1 inch
• Mounting: Peel-and-stick rubber backing

Applications:

• Easily interfaced with microcontrollers, Arduino boards, Raspberry Pi, etc., using an Analog to Digital Converter (ADC).

This sensor is ideal for simple force-sensing applications, but its accuracy limitations mean it’s better for detecting presence or pressure rather than precise measurements.
