Internet Of Things Technology In The Warning Of Fire Systerm

Wireless automatic fire alarm system security in the building of modern society plays a very important role.As the development of wireless internet of things,security development will be the first involved in the field. Fire prevention is also an important matter of the application of wireless internet of things. Sensor applications are increasingly widespread, especially in the application of infrared sensors has received considerable attention. The subject of the main use of pyroelectric infrared sensors has received considerable attention. The subject of the main use of pyroelectric infrared sensors and wireless internet of things to achieve things hidden dangers of fire detection system.In this paper, it is mainly introducing how to use 51 single chip realizing wireless automatic fire alarm ,including the hardware platform designing, electronic components and how to select the main driving chip select, and software process designing and so on. In the process of achieving, the main research of this subject matter of wireless networking technology, infrared sensors, Zigbee technology and temperature calibration and other important basic principles of theoretical knowledge. This article introduces the key technologies of wireless Internet of Things technologies, including RFID technology, location technology, time synchronization technology works. Principles of infrared temperature sensors have made the corresponding description, and the process of infrared temperature sensor calibration and temperature calibration principle to achieve the research process in detail.
