Abstract

Trains are a means of public transportation that is very popular with the general public, especially for the middle and lower classes. One of the main factors in the comfort that train passengers receive is the availability of a water source on each train to meet passengers' needs. The availability of water sources itself is very dependent on the ability of a train engineer to regulate the rhythm of filling water in a water tank which gets its water supply from sources located at each train stop station. So the author wants to increase the work efficiency of technicians to make it more concise by monitoring smartphones so they can monitor the status of the water level on the train ladder. The design of this system uses Arduino Mega as a controller which is connected to NodeMCU and a Water Level sensor where the control system communicates with each other between carriages using a Firebase datalogger. Technicians will get this data in real time by creating a smartphone application for monitoring using the MIT App. Testing the tool obtained accurate data and results that were in accordance with the design.
