I need suggestions

please help me, thank you for your time.

 

Choose the one you feel more confident about.

 

The water pump will be reliable and less of a chance for intermittent signals and false triggers.

For a sold looking design, go with the water pump.. besides moving stuff looks cool in front of the instructor and class.
