Development of Internet-of-Things based Building Monitoring System for Supporting the Disaster Mitigation in The City

A modern city is characterized by many buildings for commercial and residential purposes. Disaster mitigation such as building fires, earthquakes, and so on should be taken into account in city management. Mitigation seeks to reduce the level of risks when a disaster occurs. A proper mitigation requires an early warning system to alert the city authority in order to handle a disaster effectively. This paper describes the prototype of a building monitoring system using an internet-of-things platform for supporting the disaster mitigation in the city. It employs a temperature sensor, a smoke sensor, and a vibration sensor to detect the condition of temperature, smoke concentration, and the presence or absence of vibrations as an indication of an earthquake respectively. All sensor data is pooled in XBee transmitter module to broadcast into XBee receiver module. The data is sent continuously through the ESP-8266 module such that an internet-of-things platform called Cayenne will proceed the data by displaying the condition of building and alerting a warning message. If there is an indication of a fire or earthquake, then such message will be displayed in the Cayenne dashboard and sent to the registered mobile phone number. Experimental results show the Cayenne dashboard can display data related to the condition of the building at any time and a warning message can be displayed whenever indications of a fire and earthquake.
