• Analysis of data
  • Board still transmits data
  • We believe we're getting wrong Apogee data
  • 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

• 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.

• 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)
