Preliminary demonstration of results from a homemade GPS Datalogger w/ environmental sensors.
Arduino Leonardo, Adafruit Ultimate GPS Shield, a few Adafruit Trinkets, a CO sensor, microphone, dust sensor, and a ton of coding….
I attached the sensor box to the roof of my car w/ the GPS antenna, put an SD card in the logger, and drove around downtown Chicago for about 80 minutes collecting data.
I combined those results with real-time traffic congestion data downloaded from data.cityofchicago.org inside ArcGIS, tweaked the presentation with ArcScene, and came up with this short video….
With Arduino UNO & this setup, I can now:
get sensor values from the Trinkets and GPS shield
log the sensor data to the SD card
log the GPS data to the SD card
not do all of the above within the same sketch
Pretty sure I’m running out of SRAM. If I’m correct, I’m about .5k short of what I need.
So….on my way to buy an overpriced Leonardo (from local store) to swap in.
