Design and constructrion of water levels monitoring equipment a hydropower dam based on internet of things (case study: Way Besai hydropower plant in West Lampung)

A Hydropower Plant is one of the generators that is driven by using kinetic energy, by utilizing the flow of flowing water, by converting the flow of water into kinetic energy so that it can rotate the turbine, the kinetic energy of the turbine is converted into energy of generator motion. Hydropower have dams/reservoirs as temporary water storage from upstream of the river, by using dams the stored water can be helpful for hydropower generation. But because the weather characteristics in Indonesia can cause river flow instability which can cause river discharge to change suddenly if conditions are dry season or rainy season to overcome problems when the river overflows with the application of the internet of things, applying real-time water level monitoring technology. The application of the internet of things to hydropower dams can help residents and State Electricity Company employees to monitor the water level. Monitoring tools can display water levels in real time through mobile applications, charts, and databases. The data shown in the database can be downloaded as a data sheet. The graph is displayed using the Thing speak web server according to the sensor data installed on the dam with the results of the Wemos R3 microcontroller test getting an average peak load data at a height of 370 cm which causes low tide in the Way Besai hydroelectric dam.
