Sistem Solar Cell Untuk Cadangan Suplai Energi Listrik Pada Sistem Kontrol Budidaya Tanaman Hidroponik Selada (Lactuca Sativa) Berbasis Internet Of Think (IoT)

Abstract

The technique of growing hydroponic plants uses water that already has the nutrients the plants need. The success of hydroponics depends on the care applied to these plants being appropriate and effective. First and foremost, adequate nutrient water circulation, on time and with appropriate pH. However, as a plant owner, there are various activities during the care process which are not always under your control. A good method to use is hydroponics, namely NFT (nutrient film technique). However, the NFT method requires the water flow to be maintained so that the nutrient water can be channeled to the plant roots. This means that the pump must work constantly to maintain the smooth circulation of nutrients in the water. But if PLN, which is our energy source, loses its energy supply, the pump cannot distribute nutrients. So a solution is needed. The solution presented in this research uses the Internet of Things (IoT), utilizing NodeMCU esp32 which functions as the main processor and can send data from sensors to users, so that owners can monitor and control the condition of hydroponic plants even remotely. including creating backup energy from solar energy as a solution if the energy supply from PLN goes dead.
