Abstract :
Determination of analysis of sea level detection devices with short message service
media aims to make prototype gauges of surface water levels used as media for early
warning of floods. 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.
