Rancang Bangun Alat Pengering Emping Melinjo Berbasis Arduino

This dryer uses a drying system of incandescent lamps and sunlight which is still dependent on the weather, therefore an automatic drying system is made which is controlled using the Arduino program which is able to adjust to all weather conditions. To be more effective, this tool uses a solar panel system as a voltage source used in drying melinjo chips, so it can save electricity consumption at home, no need to use a lot of power in drying melinjo chips because the solar panels themselves get electrical energy from the sun which is absorbed through the cells. cells in the solar panel layer that are stored through a battery / battery. In the research that has been done, the author uses the research method "Research And Development" which means research and development. This system uses a DHT22 sensor to determine the temperature in the drying box space. HX711 loadcell sensor to determine the weight of the rack load when used for drying. Furthermore, the light intensity sensor BH1750 functions to turn on the incandescent lamp when the ambient light intensity begins to fall. The FC37 rain sensor functions to automatically move the top cover when it rains. Solar panels are used to save energy consumption at home. The result of this research is an Arduino-based melinjo chips dryer. This dryer can be used when the weather is uncertain which is controlled from the sensor, the sensor has worked normally. From the results of drying the tool compared to sunlight, the difference in drying time is up to 50%, this dryer is good enough to use. The solar panels have also worked well to store power in the battery which has a capacity of 45 Ah
