The design of this prototype tool uses the arduino programming application, sim900A for communication media between the main monitor and the handphone, and a water float sensor to detect water levels. The results of the analysis of testing conducted 3 consecutive days with different times, on sensors 1,2 and 3 stated safe passing via sms.} }
