Abstract
Weather information is important for humans. The high rainfall on Bengkalis island must be predicted to prevent extreme weather phenomena, including storms, heavy rain, and snow, which have potential to cause disasters. This has an impact on the safety of ship transportation on Bengkalis Island. Thus, a sistem was develop to monitor weather in real-time by using the Internet of Things. The system consists of an Arduino Mega controller and seven weather parameter measuring sensors (temperature, humidity, air pressure, light intensity, wind speed, wind direction, and rainfall). This system is equipped with a SIM800L GPRS module to connect data to the Firebase real-time server for the purpose of displaying the data on the Android application. Based on the test results, the DHT-22 sensor had an average error of 0,61% in temperature testing and 0,48% in humidity testing. The wind speed sensor test had an average error of 4,11%. The BH1750 sensor test had an average error of 3,58%, while the BMP280 sensor test had an average error of 0,035%. In the wind direction sensor test, each direction obtained an angle of 44 degrees, with the exception of the north direction which obtained an angle of 45 degrees and the northeast direction obtained and angle of 43 degrees. While the rainfall sensor had an average rainfall value of 1,580 mm on each sensor tip. This research has successfully developed a real-time weather monitoring system at the Bengkalis State Polytechnic Campus. The system enables users to conveniently monitor the weather conditions at the Polbeng campus and Bengkalis Island at any time and from any location using only an android smartphone.
