The 7Semi RS485 Air Quality Sensor is an industrial environmental module designed for stable measurement of temperature humidity and volatile organic compounds. Its digital sensing core delivers consistent output for applications that require long term monitoring and reliable field performance. The sealed probe structure reduces dust interference helping maintain accuracy in varied installation environments.
Integration is simplified through RS485 Modbus RTU allowing direct connection to PLCs SCADA IoT gateways microcontrollers and building automation systems. The wide 9 to 36V DC supply range and software configurable Modbus address and baud rate make it suitable for industrial control panels remote data loggers HVAC systems agricultural monitoring nodes and environmental stations.
