The 7Semi RS485/MODBUS RTU Industrial Environmental Probe is designed for industrial environmental monitoring by measuring air quality, volatile organic compounds (VOC), temperature, and humidity. Built with a digital sensing core, the probe provides stable and consistent measurements for long-term monitoring applications. Its sealed probe construction with a breathable, dust-proof design helps maintain reliable performance in demanding environments.
The probe communicates using the industry-standard RS485 Modbus RTU protocol, enabling seamless integration with PLCs, SCADA systems, IoT gateways, microcontrollers, and building automation systems. Operating from a wide 9–36V DC input range, it is suitable for industrial control panels, remote monitoring systems, HVAC installations, agricultural monitoring nodes, and environmental monitoring stations. Software-configurable Modbus address and baud rate simplify deployment across different automation systems.
The sensor measures VOC concentrations from 0 to 1000 ppm and provides both two 16-bit raw VOC signals and a processed VOC Index ranging from 0 to 500. Temperature and humidity measurements are delivered with high accuracy and fast response times, making the probe suitable for continuous indoor environmental monitoring and industrial air quality applications. The four-wire interface simplifies installation while ensuring reliable communication over RS485 networks.
The 7Semi RS485 Industrial Environmental Probe is suitable for HVAC systems, indoor air quality monitoring, building automation, industrial automation, smart agriculture, remote data logging, and environmental monitoring applications. Its rugged probe design, industrial communication interface, and fast sensor response make it an effective solution for monitoring critical environmental conditions.
