I am in the process of designing a throttle for my electric boat. As of now, I use a slide potentiometer, but I doubt it will last very long. For a long-term solution I am looking for an angle/rotation sensor with no moving parts (so, no regular potentiometers). Sensors based on measuring the magnetic field from have long life. I suppose an LDR with LEDS would work as well.
I have tried putting magnets inside an old throttle and a positioned a Hall sensor statically in the middle (I know -- messy cables ):
It works, but it is not perfect. Of course it is just a matter of limited mechanical design (a 3D printer would help, but I do not own one) and not the idea itself.
To get more accurate reads, I am looking at manufactured products. The Clarostat HRS100SSAB090 [1] is about $30 - $50 and seems to be a nice product, but it is not available in 270° and the 180° seems to be tirelessly out-of-stock. I would like to have more suggestions.
