It is ideal for integrating into tight spaces where precise force measurement is needed, such as wearable tech, medical devices, or robotics fingertips. Its thin, flexible design allows easy mounting on curved surfaces and provides reliable readings for both momentary contacts and sustained pressures.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensing Area Diameter\u003c\/td\u003e\n\u003ctd\u003e5.08 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eForce Range\u003c\/td\u003e\n\u003ctd\u003e0.1 N to 20 N (approx. 10 g to 2 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eActuation Force\u003c\/td\u003e\n\u003ctd\u003e~0.1 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e0.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance (No Load)\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;10 MΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V–5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSimple digital weighing scale with an Arduino and LCD display\u003c\/li\u003e\n\u003cli\u003eTouch-sensitive button that triggers an action when pressed\u003c\/li\u003e\n\u003cli\u003eInteractive stress ball that controls LED brightness based on squeeze force\u003c\/li\u003e\n\u003cli\u003eCat detection mat that sends a notification when your pet sits on a cushion\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis sensor works with any microcontroller that has analog input, including Arduino Uno, Nano, Mega, Raspberry Pi Pico, and ESP32. For Raspberry Pi single-board computers, an external ADC (like MCP3008) is required. It operates at 3.3V–5V, making it compatible with most maker boards. Common pairings include the ADS1115 for I2C-based 16-bit readings.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect one terminal to Vcc (5V or 3.3V), the other terminal to ground through a 10kΩ resistor, and tap the junction to an analog pin. The resistor value can be adjusted (1kΩ–100kΩ) to shift the sensitivity range. Ensure connections are secure; soldering directly to the thin leads may damage the sensor—use a connector or conductive tape.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, absolutely. The force sensor works with any Arduino board that has analog inputs (Uno, Nano, Mega). Simply wire it with a pull-down resistor and read analog values.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I measure pressure in pounds or kilograms?\u003c\/summary\u003e\u003cp\u003eThe sensor responds to force, not pressure over area. For a 5.08mm circle, 20N ≈ 2kg force. You can calibrate it using known weights to display in your preferred unit.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the typical lifespan of this sensor?\u003c\/summary\u003e\u003cp\u003eUnder normal use (up to 10N for millions of cycles), it can last for years. Avoid exceeding the max force repeatedly or exposing it to moisture.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
