ZIGBEE BASED WEATHER DISASTER ALARM MONITORING SYSTEM

Natural disasters are becoming more severe. To care fully protect people in these areas,we need a weat her monitoring and alarm system. In many events such as landslides and water flooding,they can be warned by a raised alarm within a specified period. The system with su ch facility equipment is a tool used to measure par ameters such as sample temperature,air pressure,moisture,vibr ation etc. These parameters will vary depending on the requirement of the surveillance system. From the weather station research,it was determine d that the most important factors for performance p rediction are temperature,humidity,and barometric pressure,whi ch are used to calculate corrected altitude. To ach ieve the necessary precision for a corrected altitude predic tion,accuracies of 0.1�F,.1 in Hg,and 10% RH fo r temperature,barometric pressure,and relative humidity,respect ively,are required;however,greater accuracy prod uces better result. https://www.ijiert.org/paper-details?paper_id=14052
