I have a readymade water level sensor atm btw. Cost me crap, literally. I can send you what's required for it and some pics too. Other one is a sensor alarm. Pretty common. Me and my friend worked on that.

Personally, sensor is much easier than a pedometer. However, if you want a good grade, I suggest you build my dream- Iron Man

I won the science expo just by putting a flashlight on a dog and saying it will keep you from losing your dog at night...
