Automation of humidity in the greenhouses for plant cultivation

Abstract

Greenhouse is a building formed to protect and care for plants from various kinds of weather and pests on plants. In addition, greenhouses also function to manipulate and control environmental conditions so that the conditions needed for plant growth are met. Air humidity is one of the environmental conditions that affect plant growth and can be controlled by automatic fogging so that plants can grow optimally. This research aims to produce an atomization system and maintain air humidity in the greenhouse automatically. The use of this research is as an information material for farming communities to control air humidity automatically in greenhouses through the use of technology. This research was carried out by designing automatic fogging to keep the air humidity value constant. The sensor test results show that the air humidity (RH) value when plants photosynthesize optimally, namely morning to evening within a 12 hour period, is around 84.17% with setting points of 80% and 90%. And the test results show that the system can maintain the air humidity value constant according to the given setting point.
