In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.As long as in addition, technical characteristic involved in the various embodiments of the present invention described below
It does not constitute a conflict with each other and can be combined with each other.
Term " first " and " second " in description and claims of this specification etc. be for distinguishing different objects,
Not for description particular order.
It is a kind of structural representation of intelligent air moisture content measuring device provided in an embodiment of the present invention as shown in Figure 1
Figure, including：Container utensil 1, measuring cylinder, electrical appliance kit 5, accumulator 7 and solar panel 6；
Container utensil 1 can be thermometer screen, for separating other devices with extraneous；
Measuring cylinder can be cylinder, and heat safe first Temperature Humidity Sensor 9, fan 2 are housed inside measuring cylinder and added
Hot water radiation wire 8, through strainer and air communication, bottom is connected and fixed with electrical appliance kit 5, while being contained outside measuring cylinder for measuring cylinder both sides
High-precision second Temperature Humidity Sensor 10 is equally placed in dress utensil；
Electrical appliance kit 5 contains controller and wireless transport module；Controller can be fixed on inside electrical appliance kit 5 through screw, electricity
Display module 4 is fixed in 5 outside of device box；Wherein, controller is warm and humid with display module 4, fan 2, resistive heater 8, first respectively
Spend sensor 9, the second Temperature Humidity Sensor 10 and wireless transport module connection；Wireless transport module is directly anchored to controller
On panel, antenna 3 reaches the external world through the punching on container utensil 1；
