{"title":"DFRobot SEN0659 Industrial RS485 NDIR CO2 Sensor - 400-5000ppm","handle":"industrial-rs485-infrared-co2-sensor-for-air-quality-monitor-ip65-ndir-400-5000ppm","url":"/products/industrial-rs485-infrared-co2-sensor-for-air-quality-monitor-ip65-ndir-400-5000ppm","description":"This industrial CO2 probe is built for reliable carbon dioxide monitoring in environments such as indoor air quality systems, pipelines, greenhouses and fresh air systems. It uses NDIR sensing to measure CO2 from 400 to 5000 PPM and supports manual calibration for dependable readings.The IP65-rated plastic housing uses a threaded fixed installation design with an M18 mounting thread, making it suitable for permanent installation. The sensor head includes a waterproof, breathable polymer membrane to help prevent water vapour and dust ingress while maintaining air permeability.Data is provided over an RS485 interface using the standard Modbus-RTU protocol, ready for integration with controllers and industrial monitoring systems. For prototyping, it can be used with modules such as DFRobot's Gravity RS485 to UART active isolation signal conversion module (DFR0845) and platforms such as Arduino UNO R3.The package includes one RS485 Infrared CO2 Sensor (400-5000ppm), and DFRobot provides a product wiki for setup reference.Features:NDIR technology, measuring range 400~5000PPMThreaded fixed installation design, easy installationProtection grade IP65, longer service lifeRS485 interface, standard Modbus-RTU protocolSpecifications:Power supply voltage: DC12VWorking current: <10mAOutput mode: RS485Measurement range: 400-5000ppmAccuracy: 400-2000ppm@±50ppm, >2000ppm@±100ppmResponse time: 5sStabilization time: 60sWorking temperature: -30~80°CWorking humidity: 5~90%RHStorage temperature: -30~80°CStorage humidity: 5~90%RHCasing material: plasticProtection level: IP65Mounting thread diameter: M18Size: 75*16.5mmSensor cable length: 1m","vendor":"DFRobot","product_type":"CO2 Sensor","in_stock":true,"options":[],"variants":[{"id":15912,"title":"Default Title","sku":"DF-SEN0659","mpn":"SEN0659","price":142.6,"on_sale":false,"in_stock":true,"available_quantity":42}]}
