How does a Phoenix America Inc. speed and direction sensor give me directional info?
The standard Speed and Direction sensors has two separate digital outputs. It uses an open collector (sinking) output, so the speed output switches from high (Vcc) to low (close to zero) when it sees a transition from “no-tooth” to “tooth present”. The separate direction output is high when the gear rotation is clockwise and low when the gear rotation is counter-clockwise.
