a program, and this program can be easily obtained in WeChat. Do not need to install,
scan code can be.
Figure 6 is the mobile side management software interface, which is mainly divided
into four parts: node selection, temperature and humidity display, fan control and
system message. Its function is consistent with PC side management software.
5 System Test
The principle, hardware design, and software design of the whole system have been
introduced above. The following will prove the feasibility of the system according to
the experimental data of the system.
Take node 1 as an example, it is necessary to start the system, energize the master
node, routing nodes and acquisition terminal nodes 1, and open the PC side management software or mobile terminal management software. Then, set the temperature
threshold of node to 28, and click the send button to send. In order to facilitate the
explanation, different states of the exhaust fan are selected for explanation. The
parameters and states are shown in Table 3.
