Real time standalone data acquisition system for environmental data

Dispensation of environmental data is gaining importance with time. Real time monitoring of environment facilitates us in identification of suitable locations for agriculture, industry and other purposes. In this paper, Arduino-UNO microcontroller based board is used to implement the data acquisition strategy and to interface both analog and digital sensors. Temperature, humidity, light intensity and gas concentration are monitored in real time and dew point has been calculated simultaneously. LabView 2015 is employed to provide the required user interface for end user. It assists in understanding the situation fast and effectively. This system also provides data for further processing and to extract the required results. System is useful for agricultural, industrial as well as living environment monitoring. For the purpose of independent weather station in standalone condition, Wi-Fi is used for data transmission which is stored in a cloud account. This data can be used anywhere in the world for different purposes.
