The co2 sensor can be found in this project

I got bored of work today and started coding on this project. I've written a few libraries and used as much C code where possible to lighten up on memory since the arduino doesn't have all that much.

I'm trying to come up with a good name for this project; something along the line of web arduino aquarium controller (WAAC).

I just posted in another topic here - i'm using a Raspberry Pi for aquarium monitoring/control. I've got a web interface up so can get to it on any mobile device, pc, tablet, etc. uses mysql database to record metrics, and a php package to do the charting, so i can see trends over time. I'm a former (rusty) C programmer so wrote the control code in C. the advantage of the Pi for me is that it is a fully featured OS - you can do anything. hooked it up to my home wifi network using a $10 usb wifi dongle. if anyone is interested, let me know and i can provide more details.

wow, the PI sounds better all the time. It's basically a mini computer rather than a micro-controller...
I'm a php guy and that's awesome that you can record the metrics onto mysql.

Well, I finally got around to the arduino controller. I'm using ajax to update the time and CO2 values in the browser. I've sped up the video speed so it's easier to see.



The arduino is a web server but it can only serve to one browser at a time. I've tried it on my iPad and it works but only if It's the only connected browser.

A vid of how you'd add a new device interface to the app.



Each device will have 2 controls or conditions to control it. You can use one or both conditions to control a device.

I have a feeling this plug n play route would be too much for the arduino. I might have to go through the hardcode route but I wouldn't know until I try it out first. It is a heck of a lot more complicated than hardcoding for sure.

I made a huge advancement in the project today. Here it is running.
The leds represent relays or solenoids. It is dependent on the time event (RTC) and CO2 level I sent into its logic.



Time event is triggered every minute. Every second is too taxing I think especially, calling the RTC every second. I know it's taxing for the CO2 sensor. It is called every 6 seconds. Any faster and it tends to error out.

In the video, you'll hear me blowing into the sensor to get the CO2 up and then the led turns off.

All in all this is a hefty app for the arduino. So far it takes up 1.3K out of 2K of RAM but it's still within the limit. Yeah!

I'm back. I've been running another forum for a online university class on programming. That's done with.

I could probably do more video tuts on programming like what I did over there.

Anyway, I'm switching to the rasberry pi for this project. I'm running into hardware and software walls with the arduino.
