Imagine if a citizen science data logger solution was so inexpensive and easy-to-assemble that you could build five of them for under $180 and in less than 3 hours. What if it was so accessible and flexible that a child could use it for their first Arduino project and a citizen scientists could also deploy it underwater for over a year to monitor temperature changes?
This Arduino Pro Mini data logger shield uses a DS3231 RTC module and a micro SD card reader module. 6 analog and 7 digital pins of the Arduino Pro Mini are available for input/output customization. This data logger shield is heavily influenced by the data logger builds shared freely by others online.
This shield is my first PCB build so I am actively looking for feedback.
