Abstract
With the development of society, people pay more and more attention
to environmental quality. Flower cultivation has become the first
choice, in farming can Tao Yi sentiment, enrich life. At the same time, flowers
can absorb carbon dioxide through photosynthesis release oxygen also can purify the
air, and the flower also can absorb toxic substances such as just decoration house of
benzene and formaldehyde. So more and more people like to breed flowers. This
paper designs a kind of intelligent humidity sensing watering system. The systemwith
AT89S52 single chip computer as control chip, first started watering the
flowers before thebuzzer alarm, timing quantitative watering is to pump water the
flowers every day to open automatically at a specified time, according to the different
flowers need different quantity of water, with a button to set the watering time
length, i.e., the solenoid valve open time, the rest of the time the pump does not
turn water can not flow through, according to water the flowers;humidity control is to
use a SLHT5-1 soil moisture sensor, when the detected humidity did not reach the
setting humidity, began to water the flowers, to
the setting humidity stop watering.This system can not only on time, according to
the amount of give flower watering, can alsosave water resources, so as
to make flowers grow better.
