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

The robust infrared carbon dioxide sensor is crafted for precision and reliability, ensuring accurate monitoring of CO2 concentrations in a variety of environments. By employing Non-Dispersive Infrared (NDIR) technology, it efficiently detects CO2 levels ranging from 400 to 5000 parts per million (PPM). This sensor is perfect for applications such as indoor air quality management, pipeline CO2 detection, and environmental control within greenhouses.

Utilizing advanced NDIR technology, the sensor provides exceptionally stable and precise CO2 measurements. It maintains an accuracy of ±50 PPM for levels between 400 and 2000 PPM, and ±100 PPM for concentrations beyond this range. Its swift 5-second response time coupled with manual calibration options ensures instantaneous and accurate data. An intuitive indicator light provides immediate operational feedback, enhancing user experience.

Designed for durability, this sensor boasts an IP65 protection rating and features a threaded fixed installation design. It includes a waterproof and breathable membrane crafted from polymer material, which effectively prevents water vapor and dust ingress while maintaining air permeability. This robust design ensures long-lasting performance even in harsh environmental conditions.

The sensor seamlessly integrates with control systems using its RS485 output interface and supports the Modbus-RTU communication protocol. It can be interfaced easily with modules like the Gravity: RS485 to UART active isolation signal conversion module for quick prototyping on platforms such as Arduino UNO R3. Operating on a DC 12V power supply with minimal current draw of less than 10mA, this sensor is both efficient and versatile in its applications.
