Dragonfruit Team Meeting - September 11th, 2017
Attended: Kevin, Kyaw, Tyler
Updates
- 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
Tasks
- 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.
Goals
- Solder parts onto a new board
- Find the problems from the old board
