I am starting with something relatively basic:
- motion to monitor activity and trigger a camera
- methane detector to detect poo levels (although may have to drop this if I can't get power usage down)
- basic camera to take some simple low-res pictures
- some push buttons that I can press to indicate how many eggs I've collected each day
I'll add more sensors later as required - I'm not overly interested in automated door opening or anything - the data gathered is more interesting.
The whole thing connects to my home wifi network and pushes the data up to the web, initially this will just be graphed in ThingSpeak - if time permits I'll come up with something fancier.
Oh - and to set myself an extra challenge - I'm going to see if I can run the thing off 2 AA batteries. If I can't get the battery life I'll fallback to a rechargeable battery and solar panel.
