DB801 RJ45 RS485 Indoor Humidity & Temperature Sensor
RJ45/RS485 Modbus temperature & humidity sensor with on-site display for multi-point networked monitoring.
Key Features
- RJ45 interface for RS485 bus connection
- Multi-point networking: up to 32 sensors per network
- Standard Modbus protocol, addresses 1-255
- Built-in on-site digital display

Overview
The DABECO DB801 is an RS485 bus-type temperature and humidity sensor with an RJ45 interface, enabling multi-point simultaneous monitoring, networking, and remote transmission alongside on-site digital display. It is used for data communication in computer rooms, archives, libraries, warehousing, offices, and similar environments, and connects directly with various control equipment, display instruments, and computers. One network can monitor up to 32 points, and the built-in display screen allows direct on-site observation of temperature and humidity changes.
Working Principle
A humidity and temperature sensing element communicates over an RS485 bus via RJ45 interface using standard Modbus protocol, allowing up to 32 addressable units to be networked on a single bus (addresses 1-255) for centralized, multi-point monitoring with remote transmission and local digital display.
Applications
Benefits
- RJ45/RS485 networking simplifies large-scale, multi-point facility monitoring
- Standard Modbus protocol ensures easy integration with existing control systems
- On-site display allows quick local readings without a connected system
- Long communication distance (1200m) suits large buildings and facilities
