Design of Automatic Chili and Tomato Sprinklers Based on Arduino Mega 2560

Farmers generally do not know the amount of water needed by plants. Sometimes they also have enough time to plants regularly. Merauke Regency has a very strict climate between rainy season and dry season. During prolonged summer can cause experience drought due lack water. So, it is necessary design an automatic plant sprinkler based on soil moisture around plant. This study designed chili tomato Arduino Mega 2560 in Wasur II Village. The microcontroller used mega 2560, sensor YL-69, relay, pump probe. 3 pairs 20 cm sensors will be connected series, then plugged into ground 15 deep. As result, tool performs watering (relay on) when below 75% 70%. Furthermore, reaches 75.86%, resistance value obtained 34.58 ohms. Then 70.19%, 42.70
