A flood monitoring system using ultrasonic sensors JSN-SR04T and SIM 900A have been designed. The system consists of solar panels as a source of electrical energy, JSN-SR04T as a water level detector and SIM 900A as a sent of flood information. The test results prove that the JSN-SR04T has been able to detect 20 cm to 600 cm of distances. The results of the water level produced were 5.0314 mV/cm of sensitivity and 0,.9996 of regression value. The sensitivity states that for every 1 cm of water level there was a change 5.0314 mV of voltage and a regression value close to 1 cm indicated that the sensor was worked properly. The test results also prove that used a buoy produced a smaller of error percentage than not used a buoy, but the measurement not used a buoy can minimize errors when tested in the field. Measurement error caused by increased water discharge when it rains which can affect the buoy send a signal to JSN SR04T. The tested overall has been able to detect water levels, water level conditions and sent information, so that it is beneficial for the community to flood monitor the river flow.
