Abstract
The utility model discloses a hygrograph. The hygrograph comprises a panel, a steel needle, humidity sensors, a display screen, a microprocessor, and a power supply, and is characterized in that the microprocessor is arranged in the panel and the display screen is arranged on the panel; the steel needle is fixedly connected with the panel and provided with scales, and the plurality of humidity sensors are mounted on the steel needle in different heights; the humidity sensors are used for transmitting detected signals to the microprocessor through conducting wires; the microprocessor processes the received signals and then sends data to the display; the display screen displays the received data; and the power supply is used for powering the whole system. The hygrograph has the advantages that not only the humidity of the air but also the humidity of the soils in different depths can be measured, and also has the benefits of simple structure, convenience in use, low cost and convenience in mass production.
Description
Technical field
The utility model relates to a kind of hygrometer.
Background technology
The greenhouse gardening personnel often need measure the interior humidity of booth and the humidity of different depth soil., do not have in the market a kind of in not only can Measurement of Air humidity but also can measure the hygrometer of humidity in the different depth soil.
Summary of the invention
The purpose of the utility model is: provide a kind of in not only can Measurement of Air humidity but also can measure the hygrometer of humidity in the different depth soil.
A kind of hygrometer of the utility model comprises panel 1, draw point 2, humidity sensor 3, display screen 4, microprocessor 5, power supply 6, it is characterized in that; The described panel 1 inner microprocessor 5 of installing; Described display screen 4 is placed on the panel 1, and described draw point 2 is fixedly connected on the panel 1, and described draw point 2 is marked with scale 7; Be mounted with several humidity sensors 3 on the differing heights of described draw point 2; Described humidity sensor 3 will detect to such an extent that signal is transferred to microprocessor 5 through lead, and described microprocessor 5 is handled the signal that receives, and then data will be sent on the display screen 4; Described display screen 4 can come out the data presentation that receives, and described power supply 6 provides electric energy for total system.
The utlity model has following advantage:
1. the humidity in not only can Measurement of Air but also can measure the humidity in the different depth soil;
2. simple in structure, easy to use;
3. with low cost, be convenient to a large amount of productions.
