With the increase of modern household fire and electricity consumption, the frequency of household fires is getting higher and higher.
随着现代家庭火灾和用电的增加,家庭火灾发生的频率越来越高。
Once a home fire occurs, it is prone to unfavorable factors such as delayed fire fighting, lack of fire-fighting equipment, panic and delayed escape among the people present, which will eventually lead to major losses of life and property. 家庭一旦发生火灾,很容易出现迟延扑救、消防设备缺乏、在场人员惊慌失措、迟延逃生等不利因素,最终导致重大生命财产损失。
Discussing the characteristics of home fires and fire prevention measures is of practical significance for preventing home fires and reducing fire losses.
探讨家庭火灾的特点及防火措施对预防家庭火灾、减少火灾损失具有现实意义。
下面这个pcb方案,将交流的220v转换成直流3.3v1A输出,平时是可以当作一个正常的智能插座来使用,当有烟雾时马上报警响应。220v转5v1A这个pcb是通过二级降压到达直流3.3v输出1A的。
先220v转成12v再转5v,使用到的两个芯片:220v转5v芯片,5v转3.3v1A芯片
