RS485 Air Quality Sensor – CO₂, PM2.5 & PM10 Weather-Proof Environmental Monitor
This RS485 air quality sensor provides simultaneous CO₂, PM2.5, and PM10 monitoring using industrial-grade NDIR and laser-scattering technology. Built with a weather-proof radiation shield for reliable outdoor performance, it is ideal for weather stations, environmental monitoring, smart cities, and air-quality analysis networks.
This RS485 air quality sensor is engineered for accurate, continuous outdoor monitoring of CO₂, PM2.5, and PM10 particulate concentrations. Using a combination of NDIR infrared technology for CO₂ and high-precision laser scattering for particulate matter, it delivers stable, real-time environmental data suitable for meteorology, smart city deployments, agriculture, and industrial environmental monitoring.
A weather-proof radiation shield protects the sensing elements from UV exposure, direct sunlight, and rain, ensuring measurement stability and preventing sensor drift caused by environmental stress. Internal temperature compensation improves CO₂ accuracy across varying conditions, while the laser-based PM sensors capture fine particles with high resolution down to 1 μg/m³.
Designed for integration into RS485/Modbus systems, this sensor connects easily to weather stations, data loggers, PLCs, and IoT gateways. With a wide supply voltage range, low power consumption, and multi-parameter sensing, it offers a robust, long-life solution for comprehensive outdoor air-quality monitoring.
