ESP8266 ESP Easy MEGA 2.0

ESP8266 and SMOG part four: Sleep mode for SDS011 in ESPEasy MEGA 2.0

The SMOG sensor project became a bit complex – along with the addition of relay. In the mean time thanks to Gijs Noorlander and yours- since you build, ask and use the sensor – we got updated version of ESPEasy MEGA 2.0 for ESP8266. Why the new blog entry? That’s because Gijs added the included in SDS011 function that when sent over serial connections allows to put SDS011 to sleep. Simple, elegant solution to extend the life and quality of the measurements of the SDS011…

ESP8266 and SMOG part three: sensor protection, cloud upload

Język/Language: Polski English Last time we updated our simple SMOG sensor with display (OLED) and added BME 280 to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG. It’s time now to protect our sensor. Why do we need sensor protection? Smog sensor – it’s laser in particular – has a limited lifetime – datasheet states 8000 hours. Both the fan and the laser diode should not work continuously – because of wear…

ESP8266 and SMOG part two: OLED display, measuring conditions

Język/Language: Polski English Last time we build a simple SMOG sensor, it’s time to add display (OLED) and to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG. What will you need? Hardware working SMOG sensor from previous entry, the Nettigo store has currently promotion – use the code: DIY_SMOG_15 to get 15% off the price BME280 board – temperature, humidity and pressure – the BME280 and please mind that the board supports VCC of 5V OLED…

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…

SMOG = Raspberry Pi B z SDS011

[UPDATED 03-02-2018] SMOG sensor – 2,5 and 10 micro meter particles

[Last changes]: 07-11-2017: Additional data from richer stations, Open-Smog Integration 20-12-2017: USB power control on Raspberry Pi 3, thanks to reader 02-03-2018: New API from GIOŚ Poland SMOG is common nowadays in big cities. Let’s put together a working, precise own SMOG sensor, first for the 2,5 and 10 μm size particles. There is one issue – the choices are many, but only few are reliable, precise and have affordable price. Finally – after a log searching, I’ve chosen Nova Fitness SDS011: precision is OK fan…
