The detection range is 0 to 20ppm. The sensor module provides three output modes: I2C, UART (0-3V), and analog voltage. The probe is factory-calibrated and features an integrated temperature compensation algorithm and a threshold alarm function. The I2C address is user-modifiable (32 options). It operates on a 3.3V to 5.5V DC supply with a working current of less than 5mA. The probe has a service life of over two years in air. Compatible with Arduino, ESP32, and Raspberry Pi.\u003c\/p\u003e\n\u003cp\u003eThe probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years. The easy-to-use Gravity interface, coupled with our sample code, can quickly build a nitrogen 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 nitrogen dioxide detection\u003c\/li\u003e\n\u003cli\u003eUnderground nitrogen 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: Nitrogen Dioxide(NO2)\u003c\/li\u003e\n\u003cli\u003eDetection range: 0~20ppm\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: NO2 Signal Conversion Board x1\u003c\/li\u003e\n\u003cli\u003eNO2 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\/sen0471\/\" 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":67691448991821,"sku":"E34002-010","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-nitrogen-dioxide-sensor-0-20ppm-i2c-uart","provider":"MLAB","version":"1.0","type":"link"}
