准备一个8050三极管，先连接一个10K的电阻和一个1K的电阻，在如图位置连接一个二极管，加上一个580欧姆电阻，一个发光二极管，注意发光二极管的正负极。加上一个12伏特的电子蜂鸣器作为声音报警器，找视频中那样排列并焊接，用9伏特电源供电，红线连接正极，黑线连接负极，当检测到火苗，就会触发声光报警。一个简单的火苗检测报警器就制作完成了。
Take an 8050 transistor and start by connecting a 10K resistor and a 1K resistor. Connect a diode at the position shown in the diagram, followed by a 580-ohm resistor and an LED. Pay attention to the anode and cathode (positive and negative poles) of the LED.
Then, add a 12-volt electronic buzzer as the sound alarm. Arrange and solder all components as demonstrated in the video. Power the circuit with a 9-volt power supply, connecting the red wire to the positive terminal and the black wire to the negative terminal.
When a flame is detected, the sound and light alarm will be triggered. A simple flame detection alarm is now completed.
