Introduction: WATER SENSOR'
Make a simple circuit of a water sensor by using a few electrical devices. Don't trust just try it yourself.
They are-
1) NPN transistor.
2) Switch.
3) Two 500 ohms resistor.
4) A 10kohms resistors.
5) 0.01 capacitor.
6) 0.001 capacitor.
7) A LED ( 1.5 volt).
8) A 3 volt power source.
9) Basic tools
