This sensor leverages \u003cb\u003eNon-Dispersive Infrared (NDIR) technology\u003c\/b\u003e to accurately detect CO2 levels from \u003cb\u003e400 to 5000 PPM\u003c\/b\u003e. Its rapid 5-second response time and manual calibration support ensure highly accurate and responsive data. Key applications include indoor air quality monitoring, pipeline CO2 detection, greenhouse environmental control, and fresh air system integration.\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePrecision NDIR Technology \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe sensor employs advanced NDIR technology, a highly stable and accurate method for CO2 measurement. This enables a measurement range of 400 to 5000 PPM, with high accuracy specifications: ±50 PPM for concentrations between 400-2000 PPM, and ±100 PPM for concentrations above 2000 PPM. The quick 5-second response time and optional manual calibration capability ensure real-time and dependable data acquisition. An intuitive indicator light provides immediate visual feedback on the sensor's operational status.\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRobust Industrial Design \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eFeaturing an IP65 protection rating and a threaded fixed installation design, this sensor is built for durability and easy deployment in demanding conditions. The probe is equipped with a waterproof and breathable membrane made from a polymer material, effectively preventing water vapor and dust ingress while maintaining optimal air permeability. This robust construction ensures a longer service life and reliable performance in harsh environments.\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSeamless Integration with RS485 Modbus-RTU \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eEquipped with an RS485 output interface and supporting the standard Modbus-RTU communication protocol, the sensor offers straightforward integration into existing control systems. It can be easily interfaced with modules like the Gravity: RS485 to UART active isolation signal conversion module (DFR0845) for quick prototyping and data reading on platforms such as Arduino UNO R3, simplifying development and deployment. The sensor operates on a DC 12V power supply with a low working current of less than 10mA.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34022-content1.webp?v=1791323624\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNDIR technology, measuring range 400~5000PPM\u003c\/li\u003e\n\u003cli\u003eThreaded fixed installation design, easy installation\u003c\/li\u003e\n\u003cli\u003eProtection grade IP65, longer service service life\u003c\/li\u003e\n\u003cli\u003eRS485 interface, standard Modbus-RTU protocol\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIndoor CO2 concentration monitoring\u003c\/li\u003e\n\u003cli\u003ePipeline CO2 concentration monitoring\u003c\/li\u003e\n\u003cli\u003eGreenhouse plant environment monitoring\u003c\/li\u003e\n\u003cli\u003eFresh air system environment testing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePower supply voltage: DC12V\u003c\/li\u003e\n\u003cli\u003eWorking current: \u0026lt;10mA\u003c\/li\u003e\n\u003cli\u003eOutput mode: RS485\u003c\/li\u003e\n\u003cli\u003eMeasurement range: 400-5000ppm\u003c\/li\u003e\n\u003cli\u003eAccuracy: 400-2000ppm@±50ppm, \u0026gt;2000ppm@±100ppm\u003c\/li\u003e\n\u003cli\u003eResponse time: 5s\u003c\/li\u003e\n\u003cli\u003eStabilization time: 60s\u003c\/li\u003e\n\u003cli\u003eWorking temperature: -30~80°C\u003c\/li\u003e\n\u003cli\u003eWorking humidity: 5~90%RH\u003c\/li\u003e\n\u003cli\u003eStorage temperature: -30~80°C\u003c\/li\u003e\n\u003cli\u003eStorage humidity: 5~90%RH\u003c\/li\u003e\n\u003cli\u003eCasing material: plastic\u003c\/li\u003e\n\u003cli\u003eProtection level: IP65\u003c\/li\u003e\n\u003cli\u003eMounting thread diameter: M18\u003c\/li\u003e\n\u003cli\u003eSize: 75*16.5mm\u003c\/li\u003e\n\u003cli\u003eSensor cable length: 1m\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRS485 Infrared CO2 Sensor(400-5000ppm) 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\/sen0659\/\" 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":67580620898381,"sku":"E34022-001","price":105.74,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34022-win1.jpg?v=1791323644","url":"https:\/\/www.mlab.com.au\/products\/industrial-rs485-infrared-co2-sensor-for-air-quality-monitor-ip65-ndir-400-5000ppm","provider":"MLAB","version":"1.0","type":"link"}
