Some Applications Of Micro Sensing Technology Based On Android System

There is no doubt that big data and artificial intelligence has become the theme of information age.The collection of big data and intelligent processing can give full play to the characteristics of computer computing speed,thereby reduce the inconvenience caused by manual processing.Today,science and technology information is not limited to traditional computers,but in the pursuit of more convenient intelligent mobile terminals,especially those on behalf of Android system.On the market,Android mobile terminal not only provides rich applications,but also carries the powerful processor and various types of sensor devices,and it can collect all kinds of data and quickly handle on it.Although the Android system provides a good platform for the software and hardware with external extensibility,there is few application applied to life,take NFC(Near Field Communication,Near Field Communication,the phone's built-in sensors)sensor as an example,the development and application of NFC is not perfect,basically in the research phase.This paper is based on the above problems and use the Android platform external interface technology to design two sets of intelligent information system,to solve the problem of environmental protection in the current tourism industry and the problem of excessive nitrate levels in drinking water respectively.One set of systems uses the NFC technology and combines with directional sensor,through the NFC principle of read/write mode,we have design the intelligent tourism platform system,the system uses NFC tag(tag card)as an auxiliary equipment,users can "scan" the NFC tag to leave comments civilly,and get a prize if they find the specific tag card,.It can not only solves the uncivilized behavior of graffiti but also increases the entertainment of scenic area.Another uses Android bluetooth external interface technology and combines with electrochemical sensor(RRPE1001C)to design a nitrate intelligent detection system.The system uses electrochemical sensor to collect data from the nitrate solution,and send it to the Android mobile client via the bluetooth module HC-05.After processing the data,the nitrate content of test report will be displayed on the phone's screen,which can not only detects the current state of water quality but also prevent the adverse effects of excessive nitrate content to humans.The two parts of above are based on the sensor devices to collect data and process the data through the Android mobile,and make full use of the good extensibility of the Android platform,so that the NFC sensor chip and Bluetooth of Android internal devices are applied to the real life,serving the society.
