Looking for some help with a project....
I have a boat lift that lifts the boat via 4 large tanks. A simple vacuum motor blows air into the tanks. I need to control the airflow into each tank to have the boat come up evenly and I do this with 4 manual valves to control how the tanks fill.
I would like to automate this using a PI. My plan is to use either an IMU or inclinometer (but these seem hard to find) and then 4 sprinkler valves controlled by the PI.
My question is which sensor type do I use... all I really need is the inclination of the lift on 2 axises. Accuracy of +/- 2-3 degrees is probably good enough. I have spent a fair bit of time researching various options. I am not sure an IMU will do the job? Do I need to find an inclinometer instead - but these seem hard to find an no one really talks about them WRT to PI's.
