Hi Ahmat,
Извиняюсь, ето моя ошибка. Правилное имя LM393P. Sorry, the right name is LM393P.

Yes, me and GeoMax have PCB files for this project but they will be posted after serious tests in real fields.

What happened to the tests - 20 days have passed...?

Hi pechkata,
The boards from China are here. I hope, in next two weeks they will be assembled. The tests will be performed when the weather allows.

Hi pechkata,
It is very interesting what news you have for this problem -
"I glued 3 pieces of circuit board.
All three work differently.
One of them works like yours."
If only one board works properly - where is the problem?
