The robust infrared carbon dioxide sensor designed for precise and reliable CO2 concentration monitoring across diverse environments. This sensor leverages Non-Dispersive Infrared (NDIR) technology to accurately detect CO2 levels from 400 to 5000 PPM. 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.
Precision NDIR Technology
The 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.
Robust Industrial Design
Featuring 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.
Seamless Integration with RS485 Modbus-RTU
Equipped 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.
