Abstract:
This article presents an automatic air purifier with a dust
sensor. This air purifier can filter a small dust PM 2.5 by using a small
dust density sensor model PMS3003 with an Arduino microcontroller to
command the vacuum fan automatically. In addition, this air purifier
can also display the density value, small dust volume, PM1.0, PM2.5
and PM10.0 on the LCD display its on the machine. an automatic air
purifier can also display the 3 small dust density values through the
Blynk application on smartphone as well
