Portable Fine Dust PM10 Analyzer with Large OLED Digits

Nova PM Sensor SDS011

Arduino UNO

Graphic OLED, 128 x 64

<p >The idea was to study the air pollution by dust, and to understand the history about particle pollution sometimes spread by the governmental air monitoring agencies (pollution by cruise ships, cars, etc...). So, I bought a Nova PM sensor SDS011 from Banggood and looked how to build with it a affordable Particle pollution PM10 monitor. There was some designs on the NET, bust all with old school energy consuming LED displays, which impairs the portable use with batteries. My design uses a I2C OLED to have a bright easy to read display with BIG digits for the measurements.</p><h3 >The PM10 Measuring device in action :</h3><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/XqRAS4HjoWg" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Measuring dust PM10 particle in the air</div></figcaption></figure></div><figure><img src=https://projects.arduinocontent.cc/44c11971-3dec-4fe6-ad96-8506f42389dd.png /><figcaption>PM10 concentration in the Test Aera</figcaption></figure><p >The actual map of the official measurements in my area shows that measurements from 10 to 20 µg/m3 are realistic.....
