RP-C10-LT Force Sensitive Resistor (20g-3kg)

What this sensor is

The RP-C10-LT Force Sensitive Resistor (FSR) is a thin, flexible pressure sensor that detects force or touch intensity.

In simple words: It works like a pressure-sensitive button (but analog)

Working Principle

• It is a resistive sensor

• When you apply force:

  • Resistance decreases

  • Output voltage changes

   

More force = lower resistance

It behaves like a variable resistor controlled by pressure

Key Specifications

• Force Range: 20g to 3kg

• Type: Analog (resistance-based)

• Thickness: ~0.30.4 mm (very thin)

• Operating Temp: -40C to +85C

• Idle Resistance: >10M

Lifetime: >1 million presses

Pinout

Very simple (2 terminals):

• Pin 1 VCC (through resistor divider)

• Pin 2 Analog input (A0)

Needs a voltage divider circuit to work with Arduino

Output Behavior (VERY IMPORTANT)

Output is non-linear (not perfectly proportional)

Applications

• otics grip)

• Smart seating / weight detection

• Pressure-sensitive buttons

• Wearables (shoe pressure, posture)

• DIY touch interfaces

Special Features

• Ultra-thin & flexible

• Fast response

• Low power consumption

• Easy to integrate

Important Notes (VERY IMPORTANT)

1. Not highly accurate

• Good for relative force, not exact measurement

• Not for precise weighing

2. Non-linear response

• Requires calibration for better results

3. Sensitive to placement

• Force must be applied on active area only

When to use this

Use RP-C10-LT if you want:

• Simple pressure detection

• Touch-sensitive interface

• Low-cost force sensing

When NOT to use

Avoid if you need:

• Accurate weight measurement

• Industrial precision
