The voltage value changes from solar panel to battery voltage
We concluded this because at 'night' time the board still transmits, but the voltage is fluctuating around ~3V and in the 'day' time, the highest voltage collected at one point from the data was ~5V
We plan to take down the board within this week
Arduino current analysis code written
Once the charging chip of the new board is soldered, we can begin current analysis of the board
Updates 10/4
Analysis of Dragon Fruit Data
Again, board is still transmitting
The solar panel data column in .csv file could be the addition of both the battery and the solar panel voltage since we opened the onboard charging chip and replaced with a similar external charging chip.
We plan to graph the solar panel data vs up-time to analyze the voltage fluctuations occurring on the board.
Tasks
Review csv file for Weatherbox deployment analysis
Code an arduino to monitor current drawn by charging chip
Start soldering next week (Tyler)
Start with charging chip
Investigate short circuit current of solar panel (Kyaw)
