The New Household Sensor Sensing Network

With the development of social economy and the accelerating of the pace of life, people pay more and more attention to the quality of life. In order to satisfy people’s continuous improved requirements to the home safety, comfort and convenience, more and more household products have realized intelligent. Also the appearance of Internet of Things has made the concept of itself accepted by people and intelligent household system becomes into the network era.Based on the above two kinds of thoughts, the intelligent household system discussed by this paper is designed. This intelligent household sensing uses the central processor, which is used to collect and process the signal of all the household sensors and controllers. About the network connection, the use of the latest version of Bluetooth protocol, V4.0, which newly increased the mode of low power consumption, has reduced the power consumption of the system and greatly reduced the time of networking. The Texas instruments’latest low power consumption Bluetooth chip CC2540, which includes the low power consumption Bluetooth RF front-end and the enhanced microcontroller C8051, is used in system. This chip has the feature of abundant resources, high speed and strong anti-jamming. Also as the result of a variety of communication interfaces, it can connect to all kinds of sensors and controllers conveniently. Moreover, the system has remote alarming functions, which can transmit the data from home to cell phones and village security website by messages and GPRS through Huawei’s GSM modules. The photoelectric isolation, independent power supply and shielding shell can ensure the system has a good stability and reliability. About the software design, Bluetooth protocol uses BLE-Stack embedded low power consumption Bluetooth protocol stack, which simplifies the application program design process and increases the system real time, stability and scalability. PC software and ASP.net website are developed by Visual C#.
