Flood, earthquake, air pollution (FEAR) alert and monitoring system with wifi module

In recent years, Malaysia has seen a major flood that has submerged some part of Peninsular Malaysia. Flooding has essentially devastated a million people and lots of infrastructures are destroyed. Millions of ringgits must be spent by the government to aid flood casualties. The earthquake warning system has seen extensive use in Japan, particularly in regions where earthquake risk is significant. Due to Malaysia's location outside the Pacific Ring of Fire, this system is still hardly ever utilized by the local populace. However, since the earthquake in Aceh, Malaysia has been impacted to some degree and precautions need to be taken immediately. Air pollution is becoming a larger issue, so keeping an eye on it is critical for a better future and a healthier lifestyle for every humanity. Government actions on air quality are steadily growing, but implementation and capacity gaps hinder progress towards clean air. The lack of information and failure to deliver the message to the people about the disasters is a major problem. Consequently, people did not alert about the emergency and therefore, precautions before disaster cannot be prepared. In line with the advanced technological development, Wi-Fi technology can be implemented to overcome this problem. The objective of this project is to alert people to major disasters which is flood, earthquake, and air pollution. The FEAR (Flood, Earthquake, Air-pollution) alert and monitoring system is based Wi-Fi system will be applied in this project to alert peoples about the risk of the disaster. Unlike the existing systems, this project intends to develop a more durable system which consists of three inputs which are ultrasonic, vibration and gas sensor. For the outputs this project uses buzzer, LED and LCD. Both input and output integrated with NodeMCU that act as brain to the system.
