When bonded to a surface, its 350-ohm resistance changes proportionally to applied strain, making it ideal for building custom pressure sensors, load cells, and force measurement systems. With a gauge factor of 2.0, it offers reliable performance for engineering and DIY projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\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\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eResistive strain gauge\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResistance\u003c\/td\u003e\n\u003ctd\u003e350 Ω ±0.1%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGauge Factor\u003c\/td\u003e\n\u003ctd\u003e2.0 ±1%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGrid Material\u003c\/td\u003e\n\u003ctd\u003eConstantan\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBacking Material\u003c\/td\u003e\n\u003ctd\u003eModified phenolic\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e-30°C to +80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-digital-kitchen-scale-kit-with-arduino-uno-plus-stepper-motor\"\u003eDIY digital kitchen scale using an HX711 amplifier and Arduino\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eCustom load cell for small robotic grippers\u003c\/li\u003e\n  \u003cli\u003ePressure-sensitive mat for occupancy detection\u003c\/li\u003e\n  \u003cli\u003eMaterial stress analysis jig for engineering labs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis strain gauge works with any microcontroller capable of reading a Wheatstone bridge, typically via an external ADC like the HX711 module. Common pairings include Arduino Uno, ESP32, and Raspberry Pi Pico. For best results, use a 5V excitation and a differential amplifier with at least 24-bit resolution to detect minute resistance changes.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the strain gauge in a quarter-bridge configuration with three fixed resistors (e.g., 350 Ω each) to form a Wheatstone bridge. Use shielded, short leads to minimize noise. The signal output is in millivolts; an amplifier like HX711 is necessary before feeding into a microcontroller's ADC.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
