Design and implementation of Android phones-based home security system

Security monitoring is one of the important development direction of intelligent city in the future, and monitoring based on Android makes the application more convenient and intelligent. This paper proposes a design and implementation of the smart home system based on Android, which use the Android smart phone as home monitoring terminal, use the STM32 controller ARM with Cortex-M kernel as the core to build the hardware platform, and use ZigBee wireless sensor technology to build a home network. The hardware platform and mobile monitoring terminal communicate through the web server for data and instructions transmission. Experimental result shows that this system can collect real-time temperature, vibration and other environmental information of house, and can display the video image. When an exception occurs, this system can start the automatic alarm module, thus to avoid damage to property.
