Circuit Water Alarm with LM380
This be 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.
