Smart Monitoring of Water Tanks in KSA

Saudi Arabia has been classified by the United Nations as water-scarce country and a cubic meter of water supplied by a water tanker costs about 20 times more than water supplied through the network. This situation demands efficient use of water, especially water stored in the tank due to high cost associated. To address these problems, there is need for regular monitoring of water level to identify leakages quickly. Furthermore, occasionally oversighting of water level may lead to poor scheduling for refilling the tank. In this work, we study existing solutions and develop an Android application based on the concept of the Internet of Things (IoT) for monitoring water levels of tanks in KSA. The proposed system helps monitoring water tanks in an effective way to avoid leakage or flood of water or not knowing how much water remains in the tank. The system uses wireless sensor to keep track of the water level and triggers an alert for the user if the water level is below a threshold level or empty. The concept of IoT helps continuously to keep track using sensors. The device (ultrasonic sensor) needs be attached to the water tank for monitoring and sending the data to the application through wireless link to keep track of its level. Using the android application, the user can disable and enable the notifications. However, when the tank is empty, the sensor sends a notification to the user and an email to the respective water company for refilling the water tank in a timely manner.
