5K Force Sensitive Resistor (FSR) – Pressure Sensor for Arduino & Robotics

The 5K Ohm Force Sensor is a thin, flexible, and lightweight force-sensitive resistor (FSR) designed to detect physical pressure, squeezing, or weight. Its resistance decreases as the applied force increases, making it ideal for analog force-sensing applications.

Commonly used in robotics, wearable tech, smart interfaces, and industrial control systems, this sensor is easy to interface with microcontrollers like Arduino, ESP32, Raspberry Pi, and more.

⚙️ Specifications:

• Resistance (no force): ~5KΩ (can vary slightly)

• Force Range: ~0.1 N to 10 N (10 g to 1 kg approx.)

• Sensing Area: Typically ~12.5 mm diameter (round)

• Response Time: <1 ms

• Operating Voltage: 0–5V (analog output)

• Thickness: ~0.45 mm

• Temperature Range: -30°C to +70°C

• Durability: >10 million actuations

🔧 Key Features:

• Analog output proportional to applied force

• Flexible and ultra-thin form factor

• Easy to integrate with Arduino or other microcontrollers

• Ideal for robotic grip sensing, touch detection, load measurement, and user input devices

• Plug-and-play with basic voltage divider setup

📌 How to Use:

1. Connect one leg of the FSR to 5V and the other to analog input via a fixed resistor (e.g., 10KΩ) to ground.

2. Read varying voltage based on applied pressure.

3. Calibrate for desired weight/force threshold.
