Hello,
I'm condidering to build circuit which is controlling current flowing. when resistance becomes high/low enough, it starts to pass current through.
It could be something like this:
**broken link removed**
The only problem is that current consumption of the circuit should be somethng like few microamperes. The less, the better.
I have just very little understanding about electronics, and it seems impossible to find any good links about the subject. How to find suitable components, and which kind of circuit would be the best.
Also, buying some commercial, very low power modules made for this purpose would be OK.
Thanks already for your answers/comments,
