The sensor is durable and designed to sense static and dynamic pressure in a high respond speed. Its advantages of recording the intensity and frequency of force make it widely used in all kinds of applications, such as, pressure switch, bed monitoring system, intelligent sneaker and medical device system. These sensors are also very easy to use.\u003c\/p\u003e\n\u003cp\u003eRP-C flexible pressure sensor is made of ultra-thin film of excellent mechanical property, excellent conductive materials and nanometre pressure sensitive layers. There are thin film and pressure sensitive layer on the upper layer of the sensor, and thin film and conductive circuit on the lower layer. These two layers are glued together by double sided tape. When outside pressure applies to the active area, the disconnected circuit of the lower layer will be connected through the pressure sensitive layer of the upper layer, by which to convert pressure into resistance. The output resistance decreases as pressure increases.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0294\/1.png\"\u003e\u003c\/p\u003e\n\u003cp\u003eRP-C18.3-LT Dimension Diagram\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0294\/3.png\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eForce vs Resistance\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThickness: 0.4mm\u003c\/li\u003e\n\u003cli\u003eTrigger Force: 20g, triggered (default resistance\u0026lt;200kΩ)\u003c\/li\u003e\n\u003cli\u003ePressure Measuring Range: 20g~6kg\u003c\/li\u003e\n\u003cli\u003eStatic Pressure \u0026amp; Dynamic Pressure Measurement (within the frequency of 10Hz)\u003c\/li\u003e\n\u003cli\u003eInitial Resistance: \u0026gt;10MΩ\u003c\/li\u003e\n\u003cli\u003eActivation Time: \u0026lt;0.01S\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40℃~+85℃\u003c\/li\u003e\n\u003cli\u003eLifespan: \u0026gt;1million times\u003c\/li\u003e\n\u003cli\u003eHysteresis: +10%，(RF+ -RF-)\/FR+，1000g Force\u003c\/li\u003e\n\u003cli\u003eResponse Time: \u0026lt;10ms\u003c\/li\u003e\n\u003cli\u003eEMI: Not generate\u003c\/li\u003e\n\u003cli\u003eEDS: Not generate\u003c\/li\u003e\n\u003cli\u003eDrift: \u0026lt;5%, 2.5Kg Force, Static load 24H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eDOCUMENTS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/Thin_Film_Pressure_Sensor_SKU_SEN0293_SEN0294_SEN0295_SEN0296_SEN0297_SEN0298_SEN0299\" target=\"_blank\"\u003eWiki\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSHIPPING LIST\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x RP-C18.3-ST Thin Film Pressure Sensor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":44757227569465,"sku":"SEN0294","price":16.4,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5369\/6313\/products\/sen0294-detail-001_564x376_bbd6f780-439b-4592-b9fe-4a79cc362130.jpg?v=1683952427"},{"product_id":"dfrobot-gravity-digital-ir-receiver-module","title":"DFRobot Gravity Digital IR Receiver Module","description":"\u003ch2\u003eDESCRIPTION\u003c\/h2\u003e\n\u003cp\u003eInfrared devices are widely used, and often for remote controlled devices.

You may found some white particles on the protection foam which is the KCl crystallization from the cap. Please don't worry about the crystallization in the packing box, that's normal. Actually, since the transportation restriction on liquid, we have poured out the KCL3N solution in the cap, the slight crystallization in the packing box should be leaked since the remnant. Anyway, once you received the probe, you should store it in KCL3N solution, you can not leave it in dry circumstances.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eAPPLICATIONS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWater quality testing\u003c\/li\u003e\n\u003cli\u003eAquaculture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModule Power: 5.00V\u003c\/li\u003e\n\u003cli\u003eModule Size : 43 x 32mm(1.69x1.26\")\u003c\/li\u003e\n\u003cli\u003eMeasuring Range :0 - 14PH\u003c\/li\u003e\n\u003cli\u003eMeasuring Temperature: 0 - 60 ℃\u003c\/li\u003e\n\u003cli\u003eAccuracy : ± 0.1pH (25 ℃)\u003c\/li\u003e\n\u003cli\u003eResponse Time: ≤ 1min\u003c\/li\u003e\n\u003cli\u003epH Sensor with BNC Connector\u003c\/li\u003e\n\u003cli\u003epH2.0 Interface (3-foot patch )\u003c\/li\u003e\n\u003cli\u003eGain Adjustment Potentiometer\u003c\/li\u003e\n\u003cli\u003ePower Indicator LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eDOCUMENTS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/wiki\/index.php\/PH_meter(SKU:_SEN0161)\" target=\"_blank\"\u003eWiki (PH meter)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/www.thingiverse.com\/thing:1463183\" target=\"_blank\"\u003epH and EC Probe Holder 3D Model (by Rayuela)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0161\/pH%20meter%20V1.0%20SCH.pdf\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0161\/ph%20meter%20V1.0%20layout.pdf\" target=\"_blank\"\u003ePCB layout\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0161\/PH%20composite%20electrode%20manual.pdf\" target=\"_blank\"\u003ePH composite electrode manual\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0161\/phMeterSample.zip\" target=\"_blank\"\u003eArduino sample code \/ ph sensor arduino\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/SEN0161\/DFRobot%20SEN0161.zip\" target=\"_blank\"\u003eZips for all above\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSHIPPING LIST\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Gravity: Analog pH Sensor \/ Meter Kit For Arduino\u003c\/li\u003e\n\u003cli\u003e1x pH probe (BNC connector)\u003c\/li\u003e\n\u003cli\u003e1x pH sensor circuit board\u003c\/li\u003e\n\u003cli\u003e1x Analog cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":44757253357881,"sku":"SEN0161","price":54.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5369\/6313\/products\/gravity-analog-ph-sensor-meter-kit-for-arduino-1.jpg?v=1683952710"},{"product_id":"dfrobot-gravity-ir-kit-for-arduino","title":"DFRobot Gravity IR Kit for Arduino","description":"\u003ch2\u003eDESCRIPTION\u003c\/h2\u003e\n\u003cp\u003eThis IR kit provides a remote control capability to your project.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eDOCUMENTS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/IR_Kit_SKU_DFR0107_\" target=\"_blank\"\u003eWiki\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0107\/IRremote.zip\" target=\"_blank\"\u003eArduino Library\u003c\/a\u003e (Compatible with Leonardo)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSHIPPING LIST\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x IR Remote Controller (With battery CR2025 inside)\u003c\/li\u003e\n\u003cli\u003e1x IR Receiver Module\u003c\/li\u003e\n\u003cli\u003e1x Digital Cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":44757255160121,"sku":"DFR0107","price":16.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5369\/6313\/products\/aa.jpg?v=1683952286"},{"product_id":"digital-luminosity-lux-light-sensor-bh1750","title":"Digital Luminosity Lux Light Sensor BH1750","description":"\u003ch2\u003eDESCRIPTION\u003c\/h2\u003e\n\u003cp\u003eThis Digital Luminosity \/ Lux \/ Light Sensor BH1750 sensor has built in 16-bit AD converter with direct digital output, omitting the need for complex calculation and calibration.
