DIY Automatic Dispenser (No Arduino)

Hello,
I’m trying to find out if I can get these components to make an automatic dispenser for water. This is not an Arduino project. I’m not sure what motion or proximity sensor listed on core electronics will be the right one for this project. Can someone help me with the ordering of the appropriate parts if they are available? This is a project for University. thank you
