Hydroponic system is one of the solutions for planting systems in an area that has a narrow land and uses water media as a planting medium. Plant maintenance innovations are carried out automatically using Arduino uno for working systems of HC-SR04 Ultrasonic sensors, DHT11 and pH sensors to measure water level, acidity and humidity.From this research, testing of the sensors used, and the results obtained are accurate responses with the output for controlling the motor as a water refill pump, plant sprinkler pump and nutrition pump. For HC-SR04 Ultrasonic sensors work with an accuracy rate of 99.41%, for PH sensors with an average accuracy of 92.7%. When the water level is 5 cm from the sensor, the sensor will instruct the pump to replenish the nutrient "off". And when the water level is 34.5cm the sensor will order the "refill" nutrient pump motor. In addition, the nutrient refill pump will also be "on" if the acidity of the water drops from PH 6. And if the humidity reaches 65% band watering will be done. This hydroponics uses 50 WP solar sell as an energy source that will fill 50 AH battery and at 388 watts of load.
