Alarm on Leak

Today we are going to do about the leak alarm, which can be placed in hard to reach places. The creation of such a signal was the incident happened at my house. Synulya unnoticed by us pulled the drain hose washing machine. The machine washed. And we were at home and did not know that we had was the bathroom and the water flowed out into the corridor. Step 1: ​We will need. We will need. Battery 3 volt CR1632 One transistor BC517,...
