Once we ordered our kits, we began construction. Although the wiring consisted of just following a printed schematic- we had to use soldering skills from Digital electronics before adding certain chips to our circuit board. We created a PCB board that would allow us to condense our sensor device in order to better fit inside of the RC Plane. After this we encountered several errors with our coding- we finally switched to a simpler design plan that prioritized the Temperature and Humidity sensors and we were finally able to collect data.
The picture on the left displays the original set up with the large Circuit Board and all of the sensors from our original kit- yet before they could be arranged on the board we had to solder the pins. On the right, Colin is preparing to solder the DHT11 sensor chip. Before we soldered with real pins we did practice with basic soldering practice kits in order to ensure our best work.
These two pictures above are of our PCB board, it allowed us to use all of our same chips and sensors, yet in a more compact way that got rid of overlapping wires and the oversized circuit board. We were even able to create this design using EasyEDA that pictured the RC plane we were using as well as our group names.
Initial Arduino simplified with pieces that only measure humidity and temperature. This was our first time switching from the PCB board to a more simplified Arduino configuration. At this point we also switched our code to make it a lot simpler and straight forward.
Final wire and chip configuration. Display was added in order to see weather and flight data: elapsed time, longitude, latitude, altitude, temperature and humidity. SD card inserted in order to store flight data and see it later. Also added was a gps chip in order to read (long and last).
