=====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
