These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSR's you should only expect to get ranges of response. While FSRs can detect weight, they're a bad choice for detecting exactly how many pounds of weight are on them.\u003c\/p\u003e\n\u003cp\u003eWe also have a version that has 10x as much force range, for when you are dealing with stronger pressures. If you are looking for more force range check out the Round High Force Sensitive Resistor (FSR) - 1.\u003c\/p\u003e\n\u003cp\u003eFSRs are made of plastic and the connection tab is crimped on delicate material. The best way to connect to these is to simply plug them into a breadboard or use a clamp-style connector like alligator clips, female header, or a terminal block. It is possible to solder onto the tabs but you must be very fast because if your iron is not good quality or you dally even a few seconds, you will melt the plastic and ruin the FSR! \u003cstrong\u003eDon't attempt to solder directly to your FSR unless you are absolutely sure you have the skills to do so.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note: Breadboard not included.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDetects physical pressure, squeezing, and weight\u003c\/li\u003e\n\u003cli\u003eAlpha MF01A-N-221-A01 model with 1\/2\" diameter sensing region\u003c\/li\u003e\n\u003cli\u003e50% lower cost than previous Interlink 402 FSR model\u003c\/li\u003e\n\u003cli\u003eResistive value changes based on applied pressure (measured in ohms)\u003c\/li\u003e\n\u003cli\u003eLow cost and easy to use\u003c\/li\u003e\n\u003cli\u003eProvides pressure ranges rather than exact measurements\u003c\/li\u003e\n\u003cli\u003eTypical sensor variation of approximately 10%\u003c\/li\u003e\n\u003cli\u003eNot recommended for precise weight detection\u003c\/li\u003e\n\u003cli\u003e10x force range version available for high-pressure applications\u003c\/li\u003e\n\u003cli\u003eConnect via breadboard, alligator clips, female headers, or terminal blocks\u003c\/li\u003e\n\u003cli\u003eSoldering not recommended due to risk of melting plastic components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLength:: 60.4mm\u003c\/li\u003e\n\u003cli\u003eWidth: 18.33mm\u003c\/li\u003e\n\u003cli\u003eThickness: 0.56mm\u003c\/li\u003e\n\u003cli\u003eWeight: 0.9g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eForce sensitivity range: 30g～1000g (0.3N～10N)\u003c\/li\u003e\n\u003cli\u003eForce Resolution: Continuous (Analog)\u003c\/li\u003e\n\u003cli\u003eStand-off \/ Open unloaded resistance: \u0026gt;20MΩ\u003c\/li\u003e\n\u003cli\u003eForce repeatability (single part) 2%\u003c\/li\u003e\n\u003cli\u003eForce repeatability (part to part) 10% within a single batch\u003c\/li\u003e\n\u003cli\u003eResponse time: \u0026lt;1ms\u003c\/li\u003e\n\u003cli\u003eLife cycle (without failure): \u0026gt; 5 Million\u003c\/li\u003e\n\u003cli\u003eOperating temperature: -30°C to +85°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct datasheet\u003c\/li\u003e\n\u003cli\u003eTutorial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Round Force-Sensitive Resistor (FSR)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBreadboard not included.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":52217208406304,"sku":"mru1787257253590","price":2.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/round-force-sensitive-resistor-fsr_1.jpg?v=1787257258","url":"https:\/\/www.elmwoodbasket.shop\/products\/round-force-sensitive-resistor-fsr","provider":"My Store","version":"1.0","type":"link"}
