Based on the principle of electrochemistry, the sensor probe comes with strong anti-interference ability, high stability and sensitivity, and up to two years of service life. It is compatible with mainstream controllers such as Arduino, ESP32, Raspberry Pi, etc. Besides, the sensor is designed with an easy-to-use Gravity interface, and with our sample codes, you can quickly build an oxygen \/ O2 detector.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cspan style=\"color: #ff9c00;\"\u003eCaution:\u003c\/span\u003e\u003c\/b\u003e Exposure to high concentrations of solvent vapors is avoided, both during storage, fitting into instruments, and operation.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34026-content1.webp?v=1791326197\" alt=\"\"\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStrong anti-interference ability\u003c\/li\u003e\n\u003cli\u003eHigh stability and sensitivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOxygen \/ O2 generators\u003c\/li\u003e\n\u003cli\u003eAutomobile exhaust\u003c\/li\u003e\n\u003cli\u003eAir-fuel ratio detection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePhysical Quantity Detected: Oxygen \/ O2 concentration\u003c\/li\u003e\n\u003cli\u003eMeasuring Range: 0~100%\u003c\/li\u003e\n\u003cli\u003eWorking Voltage: 3.3～5.5V DC\u003c\/li\u003e\n\u003cli\u003eOutput Signal: I2C\u003c\/li\u003e\n\u003cli\u003eWorking Pressure Range: 0.5~2.0Bar\u003c\/li\u003e\n\u003cli\u003eOperating Temperature Range: -20°C ~ +50°C\u003c\/li\u003e\n\u003cli\u003eOperating Humidity Range: 0-99% RH (non-condensing)\u003c\/li\u003e\n\u003cli\u003eResponse Time: ＜5S\u003c\/li\u003e\n\u003cli\u003eLifespan: ＞2 years (in air)\u003c\/li\u003e\n\u003cli\u003eSize: 32mm*27mm\/1.26*1.06 inch\u003c\/li\u003e\n\u003cli\u003eMounting Hole Size: inner diameter 3.1mm(0.12 inch)\/outer diameter 6mm(0.24 inch)\u003c\/li\u003e\n\u003cli\u003eCompatible with Arduino, ESP32, Raspberry Pi\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGravity: AO2 Oxygen \/ O2 Sensor Signal Adapter Board x1\u003c\/li\u003e\n\u003cli\u003eAO2 Oxygen \/ O2 Sensor Probe x1\u003c\/li\u003e\n\u003cli\u003eGravity-4Pin Cable x1\u003c\/li\u003e\n\u003cli\u003eMolex 2510 - PH2.0 cable (20CM)  x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0496\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67580757246029,"sku":"E34026-001","price":148.04,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34026-win1.jpg?v=1791326222","url":"https:\/\/www.mlab.com.au\/products\/gravity-electrochemical-oxygen-o2-sensor-0-100-vol-i2c","provider":"MLAB","version":"1.0","type":"link"}
