All-in-One RS485 Modbus Air Quality Sensor – Noise, Temperature, Humidity, Light
A compact, multi-parameter air quality sensor combining environmental, acoustic, and indoor air quality measurements in a single RS485 Modbus device. Ideal for smart buildings, industrial monitoring, and environmental control systems.
This all-in-one air quality sensor integrates multiple environmental and air quality parameters into a single compact unit, significantly reducing installation complexity and wiring. Using RS485 Modbus RTU communication, it connects easily to PLCs, BMS, SCADA systems, data loggers, and IoT gateways.
The sensor continuously monitors noise levels, illumination, temperature, humidity, CO₂, TVOC, formaldehyde (HCHO), and fine particulate matter (PM2.5 / PM10), making it well suited for indoor air quality assessment, workplace safety, smart buildings, laboratories, schools, hospitals, and industrial environments.
Its digital Modbus output ensures reliable long-distance communication and high noise immunity, while the integrated design enables fast deployment and consistent data collection across multiple parameters.
