Back to my critter ridder (wildlife avoidance system that I designed).
Back to the grind as most of my other small projects are done now.
Need a way to detect vehicle speed. Thinking of a potemeter with a flapper that is mounted inside a pipe.
The flapper rotates a given amount according to the wind speed inside the pipe. Reading the resistance (ADC) connected to PIC. X amount of resistance = X speed. The trigger or ON trigger can be adjusted with a trim pot.
The flapper moves say 1/4inch then the resistance is X
BUT is there a pot that has a very low toqure rating (amount of torque to turn shaft?
thinking very little but the flapper can be weighted or enlarged for lees or more resistance.
A rotary encoder might work but??
