Temperature sensing is a good idea but i don't think that is how they do it, cause I've read elsewhere they use a capacitance detecting method taking into account that the human body behaves just like a capacitor in contact with the ground.
Oh apparently the picture shows a dual wire ESD monitor, my bad then. But there are plenty that work only with one wire and that is what i seek to understand how.
Hi @ads-ee , i've already read similar description to what is written in that website and i know that a human body acts similar to a capacitor but still i can't figure out how to use that information to concept a circuit able to detect a human body cause am beginner in electronics, i seek...
Thanks for your reply but i think you did not understand what i am really asking, what i want to understand is not how to detect a static charge but to detect whether a person is wearing the ESD wrist band or not.
Hi everyone.
I want to know how do ESD monitors work, those who detect if someone is wearing the ESD wrist band or not. The problem is that there is only one wire feedback from the wrist band so i don't know how can you measure anything from just one wire.
Thank you.
