Integrated Smart Safety Home System based on Wireless Sensor Network and Internet of Things as Emergency Preventive Efforts in Settlement Areas

Abstract

Securing settlement areas is still being carried out with the help of security guards who monitor from one house to another. However, security guards can only guard the outside of the house without knowing the conditions inside. Meanwhile, the smart home system is one of the technologies that continues to be developed to monitor the latest conditions in the house. In this work, a system that can actually monitor the condition of each house is made by integrating the technology and utilizing three main sensors, that consist to fire, gas, and motion sensors. This system has advantages in terms of the installation of hardware that is flexible and can be adjusted to the needs. In addition, security guards can also find out the conditions in each house and also get actual notifications through the application that has been designed. From the system designed it can be concluded that the system in the house is able to send information on the conditions in it when activated, including the danger conditions to activate the alarm. From the hardware testing, the sensitivity of the fire sensor node is strongly influenced by the color of the fire, the magnitude of the fire, and the detection distance. In addition, gas sensor nodes can provide a quick response when installed near the source of the leak. Last, the PIR sensor nodes can detect the movement of people in an angle of 104.8628159° with a distance of not less than 7 meters.
