How to Make a Rain Detector with Alarm Using Transistor BC547 - Breadboard

This video will show you how to make a simple rain detector from home with simple electronic components. In this project the rain detector alarm is a buzzer that make a high frequency sound when its been activated or if electricity flows into the buzzer. This rain detector detect the presence of water and because the load of the circuit is not connected, when a water touch the load, the electrons will travel into the water because the water in conductive and the circuit will be complete, in this case the load is the copper wire or electrical wire that is been attach to a cup.
Materials:
9V Battery
Transistor BC547
Resistor 1k ohms
Electrical wire
Cup
