水位传感器报警使用LM380
这是水电路，当传感器点触水或雨警告水位传感器报警。该电路有一个声音大声警告立即听到。该电路采用集成电路LM380，通常使用的功放IC的小型，寻求购买方便，也可以使用并不难。朋友扬声器选择8欧姆小型所有权利。供电电源9V尺寸到达12V所有权利。其他的细节，请参见更好的是在电路。
This be Water Sensor Alarm Circuit for warn the water level , by when sensor point touch the water orthe rain. The circuit have a voice loud warn hear immediately. By this circuit uses the integrated circuit LM380 , usual use be power amplifier IC the small-sized , seek buy easy , be usable not difficult. For friends loudspeaker choose use 8 ohm small-sized all right. For power supply source 9V sizes arrive at 12V all right. The detail is other , see in the circuit better yes.
