Abstract
This article is a presentation. Application of Solar Energy to Control the Temperature in Greenhouses with Internet of Things Misting and Operation Methods. Objective. 1. To design, build and use solar energy as an energy source, and 2. To control the temperature in greenhouses by misting and Internet of Things operation methods. The system structure consists of 1. Solar energy power system 2. The control system consists of Temperature Controller STC – 3008. Receives an analog signal from the DHT21 sensor. The test set the temperature to 35 degrees Celsius. Under operating conditions when the temperature is greater than 1 degree Celsius. The misting system then operates and stops when the temperature drops below the adjusted value of 1 degree Celsius. Solar energy design results from. The total daily energy demand was 1,780 watts – hours. Solar energy produces average of 320 watts – hours of power in one day. With a solar energy system designed to create an Stand Alone with batteries. It used a battery with a capacity of 200 amperes, voltage in the system was 24 volts. power in the system is equal to 4,800 watts – hours. Enough for the system that actually works equal to 30 minutes per day. During the system operation, the temperature in the house averaged 38.1 degrees Celsius and the average error value was 3.2 degrees Celsius. The error value is still within acceptable range and can be activated with the eWeLink app that controls the sprinkler system for watering.
