O.S.S.D.A.S v1 stands for Open Source Solar Data Acquisition System. I have been working on this project since last few months. The picture above is the not the first prototype, but the first working prototype that looks like quite complete. There will be further revisions to the hardware and software for best efficiency and accurate results. Moreover, the recorded digital data should be rich enough to reflect the real world data’s mirror.
Features:

• Logs everything into attached SD card for data analysis in PC. A typical 1GB SD card can store years of data. Data is recorded in frequency of few seconds. Enough to plot a graph to analyze performance of short periods of ten minutes too.
• Keep track of the solar panel voltage, battery voltage, charge current and other parameters
• Keeps track of other data such as temperature, etc
• Can work without the LCD and still record information to the SD card and vice versa.
