Product Information
This series of sensors are RS-485 bus type temperature and humidity sensors.
It can achieve multi-point simultaneous monitoring,
transmission,
on-site digital display and other functions.
It is suitable for environments such as computer rooms,
archives,libraries, warehousing, and offices.
FUNCTIONAL FEATURES
●Communication method:
This product adopts the RS485 interface method and uses the Modbus data communication protocol, which is widely used in the industrial field, for data communication, and can be directly connected to various control devices, display
instruments, and computers.
●Remote transmission function:
Using the RS485 interface, the maximum transmission distance can reach1,200 meters, which can realize the remote
monitoring and control of temperature and humidity.
●Networking function:
Multiple sensors are connected in series through the bus, and each sensor requires an external power supply for
separate power supply. The total endpoint is connected to the computer serial port through a digital signal converter.
It can realize multi-point monitoring with the receiving device as the center, in order to achieve centralized control
and management in a large area. Up to 32 monitoring points can be monitored in the same network.
●On-site display:
This series of temperature and humidity sensors have an extra-large display screen, which allows direct observation
of the temperature and humidity changes on the spot through the display panel.
