Abstract:
Everything in the modern human life has undergone rapid development. This development is supported by the advance of electronics and information technology.
This research develops a wireless flow monitoring system for Nile River by using the concept of the ultrasonic waves. The proposed system automatically sense the water level and then send these level values to the control room through a wireless radio frequency subsystem.
An electronic circuit has been designed and then constructed to build this system. The wireless subsystem consists of two modules, transmitter and receiver. The Transmitter module detects a collection of water levels and transmits these data to the receiver module as a database collection. The Receiver module then displays the data on a LCD monitor. Besides, a set of display LEDs has been built to display the received data level status as a scale (safe, medium critical and risky). The data level decision done depending on old database measurements. If the water level changes rapidly this considered as a dangerous, and the system will activate a buzzer to generate sound alarm.
When testing the circuit for detecting the water levels in sending and receiving the data, the results are accurate and reliable. These results encourage us to use the application to avoid the flood disaster.
