The 7Semi Industrial RS485 Temperature & Humidity Sensor Probe is designed for reliable temperature and humidity monitoring in industrial and automation environments, using Modbus RTU over RS485 for stable digital communication with PLCs, SCADA systems, HMIs, industrial controllers, and compatible microcontrollers.
The probe supports a wide 9–36VDC input range and includes onboard signal processing, making it suitable for direct integration into industrial control and monitoring systems. Its 2m cable provides installation flexibility for panel, duct, equipment, and remote sensing applications.
The RS485 interface supports long-distance communication with good noise immunity, making it suitable for electrically noisy industrial environments, while the differential bus also allows multiple devices to share the same communication line in a Modbus network.
Key Features
- Supports RS485 Modbus RTU communication for reliable integration with industrial control and monitoring systems.
