ABSTRACT

System design deployed a wireless sensor network (WSN) in the monitoring and detection of flood. The WSN architecture comprised the sensor nodes, routing nodes, and a base station that connects with each other. Manometer and optical water level sensors, microcontroller, and the SIM900 GSM module form the sensor nodes. The sensor nodes were interfaced, configured, programmed, and powered by a 5vdc integrated power supply. Three water flow rate threshold values of <100m3/h, 100m3/h, and 330m3/h were selected as “Normal”, “Warning” and “Flooding” respectively for SMS alerts. Empirical measurements were carried out and readings were collected every 5sec for 3hrs. Results showed that the microcontroller-based WSN system predicted flooding status with a 0.04% error in accuracy based on the water flow rate parameter and an average delay of 0.048sec in response time
