7Semi RS485 Modbus RTU IAQ CO2 Industrial Sensor for Air Quality IAQ, VOC, CO2, Pressure, Humidity, Temperature

The 7Semi RS485/MODBUS RTU Industrial Environmental Probe is a multi-parameter environmental monitoring solution designed to measure air quality, VOC, CO2-equivalent index, atmospheric pressure, humidity, and temperature. Built with an industrial-grade sealed probe, it provides stable and reliable performance in demanding environments while supporting continuous monitoring through the RS485 Modbus RTU communication protocol.

Designed for industrial automation and environmental monitoring applications, the probe operates from a wide 936 V DC input voltage and integrates easily with PLCs, SCADA systems, IoT gateways, and data logging equipment. The two-meter cable allows flexible installation, while software configuration of the Modbus device address and baud rate simplifies deployment across different industrial networks.

The sensor measures temperature from -40C to +85C, humidity from 0% to 100% RH, atmospheric pressure from 300 to 1100 hPa, and gas resistance for IAQ, VOC, and CO2-equivalent index evaluation. Fast humidity response, low drift characteristics, and built-in processing provide consistent measurements for long-term monitoring applications.

The 7Semi RS485 Industrial Environmental Probe is suitable for HVAC systems, indoor air quality monitoring, smart agriculture, industrial automation, weather stations, environmental sensing, industrial safety systems, and building automation. Its multi-parameter sensing capability enables comprehensive environmental monitoring through a single industrial communication interface.
