Shining Light on Pollution
A participant at the Louisiana 4-H Clover College “Tracking Toxins: Shining Light on Pollution” session, held June 21-22, 2018 at Louisiana State University, building a particulate matter (PM) detector.
The “Shining Light on Pollution” activity involves building a particulate matter (PM) detector from basic electrical components, including a breadboard, a dust sensor, and LEDs (left) and connecting the components to a programmable microcontroller (Arduino) with code that tells the Arduino to light up LEDs based on the number of particles detected. The activity and code for the Arduinos was developed by the U.S. Environmental Protection Agency and the supplies were purchased using an education and outreach grant from SPIE, the International Society for Optics and Photonics.
