Hi guys,
Microcontrollers are a completely foreign concept to me but I would like to do something interesting as a college project. I intend to make a portable air quality sensor using a gps. I would just like some closure before I decide to spend ~€100 on kit.

GPS --- Shield here and module here

Mintyboost for portable power

Mq-7 CO sensor

1. Will All these fit on a netduino board at the same time? Or would I need a breadboard for the CO sensor? Haven't physically seen anything like this before so just need to make sure :)
2. Do I need to buy a breakoutboard for the sensor? I've searched but cant find out. Why would it be needed?
3. I have abolutely no idea of wiring schematics, resistance and so on. Is there any resource in particular that you've found helpful in this regard?
4. Anything else I should be aware of?

I intend to read most of the arduino books avaiable to learn the basics before experimenting.
Thanks a whole lot for any advice!

Nope. This is to be expected, though.

2. Do I need to buy a breakoutboard for the sensor? I've searched but cant find out. Why would it be needed?


You might. If the spacing of the pins on that CO2 sensor doesn't line up with the breadboard, you will need this to "breakout" the pins to a format that you can work with (IE, put on a breadboard). That breakout board exists, which is probably pretty good hint that the sensor doesn't use standard .1" pin spacing. So yeah, I'd get it.

I have abolutely no idea of wiring schematics, resistance and so on. Is there any resource in particular that you've found helpful in this regard?


Forums. I haven't read a single textbook on EE or programming, so I can't recommend anything off the top of my head. I have, however, read plenty of Masters thesis's and the like. If you need help on a specific topic, Google for it.

4. Anything else I should be aware of?

Not that I see....

Have fun! :)

Cheers for that Chris, I do appreciate you taking the time. So I'd need to buy a breadboard because the CO sensor wont fit then? I'd love to have fun with it but may be more stress wondering if I can learn and apply everything needed before the project deadline hah!

Do you mean breakout board? If so, yeah, you will need both a breakout and breadboard. I'd say that you could probably get all the bits working in the span of an afternoon. From there, you'll just need to join everything together to make the device serve it's intended purpose.

Sorry, didn't relaise how ambiguous that was when read over!
Yes I meant breadboard.
And I'm happy to see I could get them working in an afternoon :)

Thanks Chris

No Problem :) What you are wanting to do is pretty simple. The GPS will be the hardest part, and that will just be looking around for a driver that will work. There is a thread around here started by Crispin with a pretty good looking GPS driver. You might check that out.
