Environmental temperature and humidity monitoring integrated system
Product description:
Environmental temperature and humidity monitoring integrated system
Summary of hardware system of environmental temperature and humidity monitoring integrated system
1 、 multipoint temperature and humidity data centralized acquisition module
A module can collect temperature and humidity data at 32 points.
A three core cable connection is needed between the temperature and humidity sensors.
Modules can automatically identify sensor addressing and quantity
The module uses RS485 serial communication with the host computer to ensure the high quality and efficient transmission of data
A monitoring computer can collect the temperature and humidity data of 127 data acquisition modules
Data transfer rate: supports 9600/19200/38400 baud rate
RS485 bus transmission distance: 1200 meters.
2, "1-wire bus" temperature and humidity probe introduced
Direct digital output, all sensors between three core cable (including power and ground wire) connected, wiring convenience, low cost.
The distance between the probe and the measuring module can reach 100 meters, and the wiring is convenient and simple, thereby reducing the possibility of the problem on the spot more effectively.
The probe has low power consumption and is directly supplied by the module without on-site power supply;
The wet range is from 1 to 99%, the typical precision is 3%, and the accuracy of 55% Rh is 2%;
Low humidity and low system cost;
Range of temperature: -30 DEG C to 60 DEG C, resolution of 0.0625 DEG C.

Sketch map of environmental temperature and humidity monitoring system
The monitoring area of the warehouse is larger, and the monitoring area is far away from the monitoring computer room. Moreover, the extension of the library is very long, which brings a lot of inconvenience to the placement and routing of the environment monitoring system in the library. However, if the above problems are applied, our environmental monitoring system will be easily solved. Because the set of the sensor, digital acquisition technology, it broke the previous analog system "one to one" monitoring limit, make more centralized monitoring possible, greatly reducing the wiring distance in the monitoring area, on the other hand, to improve the overall stability of the system.
Environmental temperature and humidity monitoring system
The whole system adopts digital acquisition and sensing parts, and the measurement accuracy and the quality of data transmission are greatly improved.
The system is simple and clear, which improves the security and stability of the whole system.
The system has strong compatibility and expansibility, and the hardware interface can be easily integrated into the whole monitoring system, such as smoke alarm, ventilation control, special gas monitoring and so on.
