eli5 how does a pedometer have any idea how fast im walking on a treadmill?

A pedometer does not measure speed, it counts your steps.
When you walk or run, your body moves up and down. The pedometer can feel these movements because it has a special sensor inside. On a mechanical pedometer, this sensor is a tiny seesaw that tilts with each step you take. Most people use their phones or watches today, which would use an accelerometer for the same purpose (sensing these types of movements)
Every time this seesaw tilts, the pedometer says, “Ah, that’s a step!” and adds one to the step count it keeps track of for you. So, by feeling the motion of your body, the pedometer can tell how many steps you’ve taken.
