Internet of Things Platform for Real Time Automated Safety System Based on Multi Sensor Network and Bluetooth Module

The safety of occupants in home is an essential and very important. At present, people use liquefied petroleum gas (LPG) and natural gas for cooking and heating purposes in kitchen and many other residential areas. The use of these gases is increasing in every corner of the world. It is environmentally friendly but sometimes creates serious problems and can causes death and damage properties. The evacuation process of home occupants for safety under emergency condition is still a challenge and every year, numerous deaths occur because of gas leakage, smoke, fire and electric short circuiting. To avoid these problems, we step forward and design a safety system using open source hardware platforms, that is Arduino, Raspberry pi, Bluetooth module and multiple sensors based on Internet of Things (IoT's) for real time, monitoring and early detection of such hazards. we also provide a graphical user interface (GUI) to users for checking the status of sensors and actuators. The designed system is accessible from anywhere at any time and provides safety from electric short circuiting, intensive gas leakage, fire and explosive smoke. If the value of the interfaced sensors is greater than a predefined threshold value, the corresponding safety action will be taken automatically. The aim of this research is to cut down human intervention, reduce human efforts, minimize rate of accidents, prevent casualties and tremendous economics losses from above hazards and taking automatic decisions upon an action.
