ESP8266 and SMOG: Quick and snappy SMOG sensor with WiFi interface – first, basic version

Recently, we built a smog sensor which measures PM2.5 and PM10 ppm particles common in SMOG. This time let’s focus on something easy to do, without deliberations on extending life of the sensor. The Nova Fitness SDS011 (also versions 018 or 015) has proven to be quite accurate, with a good life expectancy, even with nearly theoretical unsupported air humidity above 70%. Today I will try to show you the mobile version of the sensor, using the cheapest elements, and then expand it with a temperature and humidity sensor, display – up to the cloud version. To start with – let’s build the basic version.

NOTICE: The ESPEasy MEGA 2.0 software that we use here – has been updated in January 2018 with much better SDS011 support. When finished with this version check out the updated one (fourth version)

This is a very easy project that can be completed withinin 10 minutes.
Flash the software,  connect 3 cables and read the result via WWW. Something that can be shown at school (or as a school project) or at the local community – as an effective SMOG meter.
