Nova Farmers is a group of oyster mushroom farmers in Pasirhalang Village, Cikarangmulya, West Bandung, which has a vertical mushroom baglog. Farmers who are dominated by women need to climb Baglog to water Baglog at every level. The purpose of this study is to design a tool that can maximize the growth of oyster mushrooms, temperature, and humidity of the kumbung to be maintained at temperatures of 28 ° C and 80% through watering. To improve watering techniques by farmers, oyster mushroom sprinklers are automatically made based on the Internet of Things that takes into account temperature and humidity factors that can be monitored and controlled through the ABUJAT android application using Android Studio software. The sprinkler section can move vertically up and down to be able to sprinkle all baglogs at each level. This system is made using a DC PG45 motor to drive the sprinkler section which is controlled by DOIT ESP32 DevKit V1 as a microcontroller and combined with a DHT22 sensor as a temperature and humidity sensor, DS1307 RTC module, water sensor, buzzer module for watering the alarm notification, 12VDC pump for pumping water, 16x2 LCD to display sensor values, limit switches, and BTS7960 motor drivers. Based on the results of the experiment, our application can function properly and can be used by Nova Farmers.
