大家好,教大家制作一个简单的水满提示装置。只需三个简单的元器件就能制作一个水满提示装置,再也不用担心水溢出来了!我们知道厨房安装有净水器,净水器会产生废水,想利用起来,放一个小桶来装水,但又怕平时没有注意水满出来,我们就想设计一款电路,当水到一定的界限时由蜂鸣器或者LED灯来提醒。于是有了水满提示装置。只需三个元器件,8050NPN一个,发光二极管一个,蜂鸣器一个。焊接好并成为三极管开关电路。接下来就是泡沫装置,这个所要的材料有:一根铁条绕成的U形,泡沫、一片金属片、两个绕成S型的两根导线,一块木块。整个装置的原理是:当水位上升泡沫开关闭合时,三极管的B极接高电平,三极管导通,LED灯亮,蜂鸣器响起来,当断开时,三极管的B极断电,三极管截止。LED灯灭,蜂鸣器不响。起到提示作用。盐城热继电器AD16系列蜂鸣器代理品牌制备电磁铁M:在长约6厘米的铁螺栓上绕100圈导线。
