| - | ==== Updates ==== | + | ==== Updates ==== |
| - | * Board still transmits after 2 days | + | * We cut the connection to the on-board charging chip and a adafruit charging chip is currently being used to power the board |
| - | * battery voltage odd (87 mV reading) | + | |
| - | * there is no solar panel but panel voltage is 3.2V (varies) | + | |
| - | * This board has the charging circuit removed from it, and we are using an actual charging chip to supply power | + | |
| * We need to figure out where the board is getting these odd readings from | * 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 | ||
| - | ==== Tasks ==== | + | Update: 9/13 |
| - | * See if old dragon fruit board is working | + | * We've figured out the why the board is reading "odd" solar test voltage. |
| - | * Can confirm that board still transmits when in lab | + | * The output of the charging circuit is soldered to the VCC input of the board, which the solar test voltage is reading from |
| - | * Test outside with solar panel and probe the board | + | * 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 | * Make sure we have the new parts for another board | ||
| - | * Where is the board reading the solar panel and battery charge data? | + | * Deploy the board without the solar panel to see if the board works. |
| - | * Deploy the board without the solar panel to see if the board works | ||
| - | * Solder crimp connectors to APOGEE solar sensor | ||
| - | * Send email to Dr. Garmire when board is ready to be tested at the rooftop | ||
| ==== Goals ==== | ==== Goals ==== | ||
