Design of greenhouse monitoring for hydroponic based on microcontroller and android system

Food crisis can hamper economic growth and progress of a nation. According to the World Food Program data in 2017 stated that 87 million Indonesians are still vulnerable to food security. In addition, agricultural land in urban and rural areas is increasingly narrow so that the food crisis cannot be prevented. Therefore, making greenhouse is used to increase food productivity in Indonesia. This greenhouse is equipped with temperature, humidity and light controls as well as a roof that can be opened and closed so that the condition of the greenhouse can be set as desired. And conditions in this greenhouse are also monitored using the Android application. From the test results, greenhouse monitoring based on microcontroller and android system can work in accordance with the desired program instructions.
