Abstract
In recent years, there has been a rapid development in the wireless technology, and then wireless sensor network (WSN) have become indispensable part of the smart home. This paper presents the wireless sensor network system is established by integrating temperature and humidity sensor, smoke sensor and wireless transmission modules ... etc sensors, and the goal of this study is to establish smart indoor security surveillance and intelligence automation systems by using wireless sensor networks, such as 2G, 3G, Bluetooth 4.0, ZigBee, Wi-Fi and GSM / GPRS ... etc wireless sensor networks. This paper is based on fuzzy logic of safety environment to design graphical user interface. Using the concept of sensor fusion, environmental sensors are used to detect environmental information that stored in the database for data processing with analysis of fuzzy logic. Predicted for fire hazards and made determination for the level of human safety hazards by analysis of sensor fusion. Warning window reminders for fire hazards allow users to timely monitor the current information of environment. In the Bluetooth technology, there are five functions for APP functional design, including temperature and humidity sensing function, human infrared sensing function, relay function, triaxial acceleration sensing function, LED light control, and voltage / current PWM control. In the ZigBee technology, the main functions for APP functional design contain Smoke, or Gas and CO…etc sensing function in order to monitor the safety of the indoor environment.
