The top layer is a flexible film with a pressure-sensitive composite; the bottom layer is a flexible film with printed conductive traces. Ideal for Arduino prototyping, sleep monitoring, smart footwear, pressure switches, counters, medical devices, robotics, and industrial process control.\u003c\/li\u003e\r\n         \u003cli\u003eDurable \u0026amp; stable: Tested with a 6 kg weight impact, rated for millions of cycles. Low drift and tight tolerance: individual sensor resistance 3%. Activation time \u0026lt;0.01 s; response time \u0026lt;10 ms. Trigger force 20 g. Default trigger condition: sensor resistance \u0026lt;200 k. Operating temperature: 40 C to +85 C.\u003c\/li\u003e\r\n         \u003cli\u003ePacking: Each plastic box contains 4 film pressure sensors. Thickness 0.4 mm. Sensing range: 20 g6 kg. Built on a flexible PET substrate for conformal mounting on curved or flat surfaces without loss of sensitivity. Sensors are used in series with a fixed resistor; measure the voltage across the fixed resistor: Vout = Vcc * R0 \/ (R0 + RS) As a rule, choose the fixed resistor R0  1\/3 to 1\/2 of the sensors application resistance range. Selecting an appropriate fixed resistor can make pressure vs. output voltage approximately linear over a certain pressure range.\u003c\/li\u003e\r\n         \u003cli\u003eUsage instructions: Install the sensor on a solid, flat, and smooth surface. Protect it from sharp objects. Use a cover layer (polycarbonate film or elastomer) for protection. The sensor material is not recommended for direct liquid contact and requires waterproofing if exposed. Overload will not permanently damage the sensor; it will return to normal operation after the load is removed. For designs involving motion, use soft rubber or a spring as part of the trigger mechanism.\u003c\/li\u003e\r\n         \u003cli\u003ePressure-threshold switch application: A typical threshold switch circuit uses a Wheatstone bridge and a voltage comparator. When pressure increases and the sensor resistance drops below R1, the comparator input U1+ exceeds U1 and the comparator output goes high. The high output can trigger downstream devices (for example, a relay to control LEDs, buzzers, motors, etc.).\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"Usdrwam","offers":[{"title":"Default Title","offer_id":47624600322199,"sku":"B0FX2754JR","price":132.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0461\/8380\/9175\/files\/B0FX2754JR.jpg?v=1775834621","url":"https:\/\/newnestshop.com\/products\/4-pcs-thin-film-pressure-sensor-0-4-mm-force-sensitive-resistor-20g-2kg-range-for-arduino-diy-industrial-precision-measurement-and-control-6kg","provider":"NewNest Australia","version":"1.0","type":"link"}
