Abstracts -Cultivation of vegetable crops using a greenhouse with the hydroponic method is a method that is widely used in Indonesia. Basically,the greenhouse condition is where the desired environmental conditions are in plant maintenance so that the plants in the greenhouse grow optimally. However, in these conditions, it is still not well controlled so that the plants are not controlled and monitored properly, causing the plants to not grow optimally. Therefore, an automatic control and monitoring system was created with the use of applications so that the greenhouse is properly monitored from any location or remotely.With the creation of an online control and monitoring system using the hydroponic application, farmers can control anywhere. Can control and monitor greenhouse temperatures, nutrients, pH and water volume in hydroponic reservoirs without having to do it manually. To monitor the greenhouse there are several sensors used
