电路红外防盗报警

电路的正告闯入者红外的系统或红外线防盗报警电路,有趣的。当有一个人传递或割断红外光。清楚该系统将当即发出正告,命令给出继电器工作,树立电流给超级警笛或其他,这个电路,然后西装是防盗报警器电路。当看到几个撰写IC 555履行的设备产生的频率驱动LED红外线的一部份发送。部份会由于光电二极管进行红外光。然后提高信号传输晶体管赋与的权力,改双电压的2倍。CA3130次变动前本次变动IC 运算放大器电路 进行比较电压模型回身。当没有信号到达传出高压出来。然而,寻求往常没有电流出来给BC109驱动继电器信号。其他的细节,查看电路中。
circuit Infrared Intruder Alarm
This the circuit warns the trespasser infrared system or Infrared Intruder Alarm circuit that interesting. By when there is a person passes or cut the light infrared. The system will clearly warn immediately, command give relay work, build current give super siren or The other , this circuit then suit is burglar alarm circuits. When see the equipment the a few compose IC 555 perform produce the frequency drives LED infrared in a part sends. The part takes as a result have photo diode perform take the light infrared. Then transmit transistor for boost up a signal gives the power goes up , and change double voltage be 2 times. Before change IC CA3130 op-amp circuits perform compare with voltage model the turned around. Be when have no a signal reaches that outgoing have high voltage come out. But seek have usual signal have no current come out give BC109 drive relay get. The detail is other see in the circuit.
