Attended: Kevin, Kyaw, Tyler

  • We cut the connection to the on-board charging chip and a adafruit charging chip is currently being used to power the board
    • We need to figure out where the board is getting these odd readings from
    • Also need to figure out if our on-board charging chip is the reason for the missing transmissions
  • Left board transmitting over the weekend in the lab to see if the board transmits well (before battery died)
    • alpha.scel-hawaii.org not working to look at data

Update: 9/13

  • We've figured out the why the board is reading “odd” solar test voltage.
    • The output of the charging circuit is soldered to the VCC input of the board, which the solar test voltage is reading from
    • As far as the board is concerned, the solar test voltage should be reading half of the voltage from the battery (voltage divider connection)
    • We've emailed Dr. Garmire about the roof top access. Waiting for his reply.

Update: 9/15

  • Battery voltage reading from the solar test pin is actually correct
    • The value is multiplied by 2 in the code when transmitted to the gateway
    • Tested sensor data values: Humidity, Temp., Solar Irradiance, Pressure
    • Ready to for deployment test next week
    • We just need to find our solar panels
  • Have to test on roof to conclude about charging circuit (working properly or not) with or without the solar panel attached
  • Email Dr. Garmire and cc Dr. Kuh for roof top access once we're ready.
  • Make sure the sensors are transmitting correct data and battery is fully charged before testing at the roof top
  • Make sure we have the new parts for another board
  • Deploy the board without the solar panel to see if the board works.
  • Solder parts onto a new board
  • Find the problems from the old board
