This is a fine dust measurement kit that measures the concentration of fine dust in the air in real time and displays the values on an LCD screen.

Additionally, you can create a fine dust indicator by using NeoPixel LEDs that change color according to the fine dust concentration.

The fine dust levels can be intuitively identified through color indicators—Green (Good), Yellow (Moderate), and Red (Poor)—making it easy to monitor indoor air quality at a glance. This kit is ideal for educational hands-on learning or environmental sensor projects.
