The Development of Automatic Weather Station Data Logger by Microcontroller Netduino

The main purpose of the research was to develop an Automatic Weather Station (AWS) data logger using microcontroller Netduino. It will be useful to each sector which affected by weather. This research implement a telemetry system on Netduino logger in purpose to place it on remote area application, beside the study was developed a switching channel method to expand the number of I/O analog pin on Netduino. A correction factor resulted by data analysis during calibration and validation using linear regression method was “0.8594x + 4.7486” with R 2 = 0.9367. This research conclude that processing analog signal on Netduino has an alteration between its real value even not significantly, some treatment has implemented to reduce the error of data output, with using good power resource and moving averaging on each data reads (FAH).
