The sensor has 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and a threshold alarm function, It has good compatibility with mainstream main control devices such as Arduino, ESP32, and Raspberry Pi. The easy-to-use Gravity interface, coupled with our sample code, can quickly build a sulfur dioxide concentration detector.\u003c\/p\u003e\n\u003cp\u003eDFRobot has introduced 12 gas detection sensors in this series, CO, O2, NH3, H2S, NO2, HCL, H2, PH3, SO2, O3, CL2, HF, which are used in exactly the same way and data format, so you can combine them according to your needs.\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\u003c\/li\u003e\n\u003cli\u003eHigh sensitivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIndustrial sulfur dioxide detection\u003c\/li\u003e\n\u003cli\u003eEnvironmental protection device\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDetection Gas: Sulfur dioxide (SO2)\u003c\/li\u003e\n\u003cli\u003eDetection range: 0~20ppml\u003c\/li\u003e\n\u003cli\u003eWorking Voltage: 3.3～5.5V DC\u003c\/li\u003e\n\u003cli\u003eWorking Current: ＜5mA\u003c\/li\u003e\n\u003cli\u003eOutput Signal: I2C, UART (0~3V), analog voltage\u003c\/li\u003e\n\u003cli\u003eWorking Temperature: -20～50℃\u003c\/li\u003e\n\u003cli\u003eWorking Humidity: 15～90%RH (non-condensing)\u003c\/li\u003e\n\u003cli\u003eStorage Temperature: -20～50℃\u003c\/li\u003e\n\u003cli\u003eStorage Humidity: 15～90%RH (non-condensing)\u003c\/li\u003e\n\u003cli\u003eLifespan: \u0026gt;2 years (in the air)\u003c\/li\u003e\n\u003cli\u003eAdapter Plate Size: 37*32mm\u003c\/li\u003e\n\u003cli\u003eCompatibility: Arduino, ESP32, Raspberry pi\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGravity: SO2 Signal Conversion Board x1\u003c\/li\u003e\n\u003cli\u003eSO2 sensor probe x1\u003c\/li\u003e\n\u003cli\u003eGravity - 4pin Cable 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\/sen0470\/\" 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":67691451809869,"sku":"E34002-012","price":299.11,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34002-win1.jpg?v=1762844224","url":"https:\/\/www.mlab.com.au\/products\/gravity-factory-calibrated-electrochemical-so2-sensor-0-20ppm-i2c-uart","provider":"MLAB","version":"1.0","type":"link"}
