4. 1. Plant will automatically be poured with liquid manure in
accordance with the soil humidity level .
2. Set up the humidity level of the soil based on the ideal humdity
level of a plant. As for example, pepper plant will grow nicely,
when its humidity level is 50% .
3. When the plant humidity is enough,which means the humidity
level has reached 50% (example for pepper plant), then the red
light will be turned on, and the DC pump will be turned off.
4. If the soil humidity level less than its requirement, then
automatically the red light will be switched off, meanwhile the
green light and the DC Pump switch on. After the humidity level is
achieved , the DC pump will be turned off as well as the green
light.

11. This is a simple water sensor can be used to detect soil
moisture when the soil moisture deficit module outputs a high level, and
vice versa output low. Use this sensor produced an automatic
plant watering device, so that the plants in your garden without people to
manage.

13. A resistor is a specialized electrical component
that provides resistance as a circuit element. Resistors
are passive, which means they are not affected by the
current they carry.

16. A diode is a two-terminal
electronic component that
conducts primarily in one
direction (asymmetric
conductance); it has low (ideally
zero) resistance to the flow of
current in one direction, and
high (ideally infinite) resistance
in the other

23. A solid-state relay (SSR) is an electronic switching
device that switches on or off when a small external voltage is
applied across its control terminals .
31. In the program it written if we have the threshold
value and the threshold value is 800 (based on which plant
we choose). Thus, when the value detected by the sensor
shows less than the threshold value , the red LED will shut
down or Off. Menawhile, green LED and the pumps would
turn on. That indicates that the plant needs to fertilization. In
reverse, when the value hits more than the mentioned value
or equal to that, red light will turn on meanwhile green light
and the pump will shut down. This indicates that the plant
does not need the fertilization.
