I need help in creating a capstone project for an ET410 course (project management)

 A typical project is to design an electronic device that would monitor a car, check that its engine is not running, then check interior temperature, then check for movement or sound. If detected sound alarm and lower the windows automatically. It should be such that the planning should take 8 weeks and 8 weeks to build. Other ideas can be anything that you want to control,  like the moisture in the soil of a green house 

I've attached the template that needs to be filled out.
