7Semi RS485 Modbus Temperature & Humidity Sensor Probe

The 7Semi RS485 Modbus Temperature & Humidity Sensor Probe is designed for accurate environmental monitoring in industrial and commercial applications. Using the Modbus RTU communication protocol over an RS485 interface, the sensor enables reliable data transmission and straightforward integration with automation and monitoring systems. Its wide operating range and precise measurements make it suitable for applications requiring continuous temperature and humidity monitoring.

Built with a stainless steel probe and a breathable dust-proof filter, the sensor is intended for long-term operation in demanding environments. It supports a 9V to 36V DC power supply, making it suitable for a variety of industrial installations. The 2-meter cable provides installation flexibility, while DIP switch configuration allows users to set the Modbus ID and baud rate according to system requirements.

The sensor measures temperatures from -40°C to +125°C and relative humidity from 0% RH to 100% RH. It delivers temperature accuracy of ±0.2°C and humidity accuracy of ±1.8% RH at 25°C, along with measurement resolutions of 0.01°C and 0.1% RH. Standard RS485 Modbus RTU communication enables compatibility with industrial automation systems including PLCs, SCADA systems, HMIs, and microcontroller-based platforms.

Suitable for HVAC systems, building automation, environmental monitoring, industrial process monitoring, weather stations, server rooms, museums, archives, and greenhouse applications, the 7Semi RS485 Modbus Temperature & Humidity Sensor Probe provides dependable environmental data for monitoring and control systems.
