The Design and Implementation of Portable Agricultural Microclimate Data Acquisition System Based on Android Platform

Aiming at the problems of high cost, large power consumption, incomprehensive coverage, boring and abstract site operation etc of the existing fixed agricultural microclimate data acquisition systems on the market, we implement a set of portable agricultural microclimate data acquisition system of low cost, small power consumption, simple and humanistic operation on spot based on android mobile phones, the Internet of things technology, bluetooth technology, sensor technology, information acquisition technology etc. The system consists of three major functional modules: foreground data acquisition terminal, android mobile phone client application program, background data control center. Data acquisition terminal sends perceptive and processed microclimate datas to mobile phones via bluetooth, then mobile terminal APP analyzes, processes, storages and displays microclimate datas, and sends the data to the background data control center through the GPRS communication. The system has been put into use in Meitan County, Guizhou Province tea fields. Results show that the system has stable performance, low consumption, low cost, simple operation, easy extensibility, and is expected to get massive expansion.
