Hi All,
Recently i am doing a fast speed (1000~4000) RPM counter using a motor's shaft with a plate and 12 slot evenly distributed on the plate.The plate is placed between a OMRON photomicrosensor EE-SX 671 .so that i can get a ON OFF signal (rising edge) when a slot is slice through the sensor.
but this idea don know really can work or not because when test with low speed (500) this work fine .but when the speed is as fast as 3000 RPM then my system can't detect the speed anymore.Does Anyone has any idea?
Thanks.
