Rain Water Alarm with LM380

Circuit Water Alarm with LM380
This be Rain alarm or Water Alarm circuit ,model to be simple. When sensor point touch the water. It is make the circuit works to have a voice warn hear. By the circuit composes the equipment is important be integrated number circuit LM380. It usual perform amplify , but for this circuit brings to pretend origin signal sound easily circuit. By have transistor edit the circuit work. And when sensor point touch the water , as a result make transistor work wasp current change LM380 give it works beep origin upwards hear. The detail is other , see in the circuit.
