I got the up/down Hall sensors in the mail yesterday and was able to set up a circuit to try one out.
I don’t think I will be able to use them.
While it does give up down pulses that moves the counter, every time I move the magnet over it, it registers both an up and down count....count stays the same. I have tried every possible distance, angle and magnet placement as well as the speed I move past the sensor. It seems to work one way if I hold it above the magnet and the other if I move it below.....but never up and down. I’m sure I have the sensor oriented in the right direction because it’s marked.
I’m using a small magnet...about 1/4” dia.
I know I am registering up down pulses because little red and green LEDs flash.
I’m going to play with it some more but it doesn’t look good. I think I will be using Diver300’s idea and will try it out when I get the reed switches.
