AUTOMATION SENSOR DHTII AS TEMPERATURE AND HUMADITY SENSOR AT HIDROPONIK BY ARDU
Created 4 years ago in Technology / Innovation

The main problem of the Indonesian people is that land is increasingly depleted with the increasing population of Indonesia. This will create problems for agriculture, because so far Indonesian citizens have used land as the main planting medium. Because of that, there were some breakthroughs in agriculture using planting media other than land, which is also called hydroponics. Of course this hydroponic has several drawbacks, one of which is the need for fairly complex maintenance. One difficulty is controlling the temperature and humidity in the environment. Therefore, in this study, the DHT11 sensor will be used as a temperature and humidity sensor for hydroponics based on Arduino uno R3 on water spinach plants. The steps that are made are (1) design design process (2) hydroponic design process (3) hydroponic manufacture (5) sensor design (6) testing. After the DHT11 sensor can detect temperature and humidity, the Arduino uno R3 will give commands to the water pump and the lights to turn on. The command is if the indicated temperature is less than 28oC then the fluorescent light will turn on. If the humidity is less than 76%, the water pump will run. After the experiment, the results obtained by the pump and lamp can be lit according to the command.
