A Survey on Flood Alert System Using IoT

Dam overflows are a constant threat throughout the year to the India. There are various methods of alerts available; such as the Emergency Broadcast System can alert a user remotely in an efficient and timely manner. The system goal of project is to provide a real- time system able to monitor sudden overflows in dam lots, addressing the concern of water damage to vehicles; creating a personal alert that could reach an end user through their mobile phone using GSM. In this case, the system defines two types of nodes sensing node and sink node. Each sensing node uses a float sensor to monitor the water levels; it will then communicate with neighboring nodes. The sink node is then responsible for sending the received data from the sensors to a control server via mobile communication network using Global System for Mobiles. Database of users which is stored on cloud and flood levels will then be processed and handled by the server, which will send users an email alert that will reach any mobile phone as a text message (SMS). India has agriculture as its primary occupation. In India of the people living in rural areas in India are dependent on agriculture. This calls for planning and strategies to use water sensibly by utilizing the advancements in science and technology. The food production needs to be increased by at least 50% for the projected population growth. Agriculture accounts for 85% of freshwater consumption globally. This leads to the water availability problem and thus calls for a sincere effort in sustainable water usage. There are many systems to save water in various crops, from basic ones to more technologically advanced ones.
