9.Matters need attention：
A.As for the use environment of WIFI, wireless signals are easily affected by the surrounding
environment. For example, obstacles such as trees and metals will absorb wireless signals to some
extent, so that the distance of data transmission is affected to some extent in practical applications.
B.It is recommended that the metal enclosure be not installed in the metal enclosure as it is shielded
from radio frequency signals.
C.PCB board: as the metal will weaken the function of the antenna, when distributing the board to the
module, it is strictly prohibited to lay the floor and wire under the module antenna. It is better if it can
be hollowed out.
