Industrial RS485 Infrared CO2 Sensor for Air Quality Monitor (IP65, NDIR, 400-5000ppm) - แท้ DFRobot

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.
