Simple project idea with arduino that monitors any condition

Hello all, I am new to Arduino and for one of my courses I have to do a project. Can you guys give me a simple project idea that monitors condition of a system or something ? For example : condition monitoring of vibration in bearing using arduino(that project I wanted to do-but faced problems). Any similar idea would be appreciated and if you have the tutorial or method I would be ever grateful to you.

Why not measure the temperature of the bearing rather than vibration?
There is a DHT11 sketch in the Sketch Builder that you could use. The DHT11 isn’t the best sensor in the world, and probably not suited to an industrial environment, but it would be a starting point for a proof of concept project.

Thanks for the suggestion. Can you help me to get the code?

Click “Sketch Builder” at the top of this page.
