Abstract :
Green house is a building where the plant has been cultivated,Green house can
be hot because of elektromagnetic radiation that comes from the sunlight which heats
the plants. In the past reseatch temprature control and monitoring has been done where
the result started that the temprature inside geend house was highther that outside in,
this final project the writer plant to control the green house temprature automatically
with the use of photo voltaic as a back up energy resourees. This automatic system use
temprature sensors that placed in the middle of the space when the temprature inside
that green house exceeds
plant watering system and the lighting in the evening. From the result we can see that
there is a differenees between inside and outside of the green house the differenees are
if the outside the green house that plant will grow up in 4 days. Where us inside the
green house the plant will grow up 3 days, from the two procesing, we can conchide
that the plantation inside the green house better than the plantation outside, of the
green house.
