基于单片机的家庭智能浇花器设计
Abstract： potted plant automatic watering system this design
including soil temperature and humidity in the detection and
control and alarm of two parts. Detection and control of part
of the soil temperature and humidity and the soil temperature
and humidity detection and display, automatic watering system.
Soil temperature and humidity in the detection and display of
temperature and humidity sensor SHT-11 as the sensing
component, soil temperature and humidity will detect the value
into the 51 micro controller(STC12C5A60S2), then the output to
the display. Automatic watering system design for intelligent
watering: intelligent watering part is compared to soil
moisture by SCM procedures set watering of the upper and lower
limits and SHT-11 into the single value, when the temperature
is lower than the lower limit value, the buzzer will alarm, then
the single-chip microcomputer can output a signal to control
the electromagnetic valve is opened, the beginning of watering,
higher than the limit value by the the single chip outputs a
signal to control the electromagnetic valve is closed, stop
watering.
