Think of it as a variable resistor controlled entirely by physical force — the more pressure applied, the lower the resistance reading at the output port. This makes integration into microcontroller projects (Arduino, Raspberry Pi, etc.) straightforward and highly versatile.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUltra-Thin Profile:\u003c\/strong\u003e Only ~0.25mm thick (0.01 in), flexible and discreet enough to embed in almost any application\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWide Pressure Range:\u003c\/strong\u003e Detects force from approximately 5g (0.2 oz) to 2kg (4.4 lb)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick Activation:\u003c\/strong\u003e Response time under 10ms for fast, real-time sensing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow Threshold Drive Force:\u003c\/strong\u003e Activates at ~2g with output resistance ≤500 KΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Resting Resistance:\u003c\/strong\u003e Greater than 10 MΩ when not triggered — minimal idle current draw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium Materials:\u003c\/strong\u003e Constructed from polyester film and high-conductivity FPC material with a nanoscale pressure-sensitive compound layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable \u0026amp; Long-Lasting:\u003c\/strong\u003e Engineered for both static and dynamic pressure sensing over extended use cycles\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact Size:\u003c\/strong\u003e 1.1 × 0.78 cm (0.43 × 0.31 in) sensing area fits tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eItem Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThin Film Pressure Sensor (FSR)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eR-C7.6-L11-LF\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePolyester Film, FPC (Flexible Printed Circuit)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThickness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~0.25mm (0.01 in); ~0.01 in with rear adhesive\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePressure Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5g – 2kg (0.2 oz – 4.4 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDriving Force\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~2g \/ 0.1 oz; resistance ≤ 500 KΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResting Resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 10 MΩ (untriggered)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eActivation Time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensing Area Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.1 × 0.78 cm (0.43 × 0.31 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 × Thin Film Pressure Sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMade in Mainland China\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eConstruction Details\u003c\/h3\u003e\n\u003cp\u003eThe sensor is a dual-layer design: the \u003cstrong\u003etop layer\u003c\/strong\u003e is a flexible polyester film bonded to a composite nanoscale pressure-sensitive layer, while the \u003cstrong\u003ebottom layer\u003c\/strong\u003e is a flexible film with a composite conductive circuit printed on it. The two layers are bonded together and isolated from the sensing area using double-sided tape (not included). When pressure is applied to the sensing area, the disconnected circuit lines on the bottom layer make contact through the top pressure-sensitive layer, causing resistance to drop proportionally to the applied force.\u003c\/p\u003e\n\n\u003ch3\u003eGreat For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eArduino \/ Raspberry Pi DIY electronics projects\u003c\/li\u003e\n  \u003cli\u003eRobotics and automation systems\u003c\/li\u003e\n  \u003cli\u003eWearable technology and smart textiles\u003c\/li\u003e\n  \u003cli\u003eTouch-sensitive interfaces and interactive surfaces\u003c\/li\u003e\n  \u003cli\u003eWeight detection and threshold-trigger circuits\u003c\/li\u003e\n  \u003cli\u003eResearch, prototyping, and educational labs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eYou May Also Like\u003c\/h3\u003e\n\u003cp\u003eLooking for more DIY and crafting supplies?

Simply connect it in a voltage-divider circuit with an appropriate pull-down resistor to read analog values corresponding to applied pressure.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need additional components to use this force sensitive resistor?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — to read analog output from the sensor you will typically need a pull-down resistor (commonly 10 KΩ) to form a voltage-divider circuit, plus double-sided tape (not included) if you wish to mount the sensor in place. No battery is included or required as the sensor is passive.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the pressure range of this film pressure sensor?\u003c\/h4\u003e\n\u003cp\u003eA: The sensor detects forces ranging from approximately 5g (0.2 oz) up to 2kg (4.4 lb). The minimum driving force to activate the sensor is approximately 2g, at which point the resistance drops to 500 KΩ or below. When no pressure is applied, the resting resistance is greater than 10 MΩ.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How thin is this pressure sensor and can it be embedded in tight spaces?\u003c\/h4\u003e\n\u003cp\u003eA: The sensor is extremely thin at approximately 0.25mm (0.01 in), making it ideal for embedding in tight spaces, under surfaces, or inside wearables and enclosures where space is at a premium. Its small sensing area of 1.1 × 0.78 cm further aids in compact integration.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.

The INMP441 microphone module is fully compatible with ESP32 microcontrollers via the I2S digital interface. Simply connect SCK to GPIO14, SD to GPIO32, WS to GPIO15, L\/R to GND, GND to GND, and VDD to the 3.3V pin.
