NOTE: This project was completed in 2019 as a part of my science fair project
SUMMARY:
This device acts as a multimeter which stores the recorded data values on an SD card. This allows the recorded data to be graphed and analyzed for your own purpose.
PURPOSE:
For one of my research projects, I needed a way to be able to record the voltage current and power produced by different sets of Solar Panels throughout the day. Because I didn't have access to an oscilloscope and it wasn't feasible for me to record data for all the sets of solar panels at the same time throughout the day. I needed to create a device that would allow me to collect the data I needed.
This is why I ended up creating a power logger that recorded the voltage current and power produced onto an external SD card. I was later able to extract the data from my SD card and graph it.
DATA COLLECTED:
The following image of the OLED shows the values recorded by the Power Logger. These values are stored as .txt files on an SD card.
