Perancangan Alat Pengering Gabah Otomatis Menggunakan Sensor DHT22 Berbasis IoT (Internet of Things)

Abstract

In Indonesia, agriculture plays an important role in meeting the basic needs of the community. However, the grain drying process is still done manually in the traditional way, such as drying in the sun. The use of a grain dryer that can regulate temperature and humidity automatically is a solution to overcome problems in the post-harvest drying process. The use of Arduino Uno R3 microcontroller and DHT22 humidity sensor can help the efficiency of rice drying. Drying grain with conventional methods under direct sunlight is less effective because it takes a long time and a large area. The use of a greenhouse effect-based dryer with the addition of black alor stone is a more efficient alternative. The grain drying process is divided into natural and artificial drying, where drying with solar energy can be optimized with the use of alternative energy. The Arduino microcontroller allows the manufacture of fluidized bed dryers that are more affordable and can increase the effectiveness of rice drying in Indonesia.
