arduino-airquality

In this project, we are building a mobile Arduino Fio based platform to measure air quality.

We currently have multiple components working correctly with the Arduino Fio:

  • GPS sensor - Adafruit Ultimate GPS Breakout v3 and the OpenLog
  • Dust sensor - Sharp Optical Dust Sensor
  • Humidity and temperature sensor - SHT10 by sensiron/DFRobot
  • Carbon monoxide sensor - Parallax CO sensor
  • Barometric pressure - BMP085 Barometric Pressure/Temperature/Altitude Sensor

We are working on combining them all into a nice light package.

Still to do:

  • Create circuit board sketch and etch it
  • Solder everything on board
  • Build enclosure

Next version improvements:

  1. Use smaller arduino board (Nano?) potentially one with GPS builtin.

  2. Decide if we want a 5V board.

  3. Use 7.4V LI-ion flat and rechargeable battery pack.

  4. Use only one voltage regulator if we stay with 3.3V.

  5. Move voltage splitter to monitor voltage to between battery and voltage regulator.

You can’t perform that action at this time.
