Angle detection

Lou_Blue

I have a boat. The engine can be tilted up or down, coving a range of around 260° from fully up to fully down. I would like a more sophisticated sensor that is better than the 5 mercury tilt switches I'm currently using, which works pretty well. This is useful for fuel efficiency and shallow water hazards.

Is there an upgrade available that I can fit in my engine?

  • Does this sensor simply indicate what angle you are manually setting the motor to, or is it used as feedback in a motorized angle setting mechanism?

    A simple accelerometer can measure angle with respect to gravity (which is what mercury switches do) - just like the accelerometer in most smart phones. It may need filtering to remove boat accelerations, or you could have one on the boat and one on the motor.

    If it is manual, you could just make a bracket to place your phone in while making the adjustment and run a tilt angle app. 

    The BBC micro:bit has a built-in accelerometer. I did a project that showed its use in measuring angles. Unfortunately all the links on this site that point to that project are broken, but here is one of the videos from that project:
