Monitoring a baby with an Arduino and some sensors. Ideas?
I'm working on my Electrical Engineering bachelors thesis and it evolved into something that I couldn't have foreseen. I'm trying to build a baby monitoring package that would involve 3 major things;
-Positions in the crib (in or out)
and all these should be controlled through a mobile app.
I have a couple of challenges. First of all there can't be wires all around the place to detect these changes and I'm not quite lost about how the package would be. I've experimented on a waterproof ds18b20 temperature sensor (got the temperature saved on a web server) and a flex sensor (thought of planting it under the crib) so far. For the breathings I thought of using a microphone but didn't really get my hands around that.
What better sensor there are that would simplify the process? What should this package consist of?
Any ideas/directions are welcome!
