Can someone help me with this? i've been working on this project and i have two US-100 and i want to use these two sensors as a counter so when people enter and pass by sensor 1 to sensor 2 increments the counter and vice versa when people pass by sensor 2 to 1 will decrement the counter. I am using arduino mega 2560 by the way.
I hawe some problem with US-100 sensor.
That's a shame.
I guess that's kinda hard to do with just 2 distance sensors. I mean, you can do it, but it won't be perfectly at all. And then it makes no sense to make this: "Ow my Arduino says that's there is still someone inside, it's probably a mistake"
