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…

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…

CCS811 & BME680 with Raspberry Pi 0 W

Measuring air quality using Bosch BME680 and AMS CCS811 – IAQ, TVOC, eCO2

Measurement of basic environmental data in our apartment – temperature and humidity is one of the most popular applications of commonly available sensors for Raspberry Pi (RPi), Orange Pi (OPi) and ESP8266. Then we added ability to measure the SMOG otuside and inside and today we will deal with two new and very interesting air quality sensors. CAUTION: Don’t forget the basics of safety – we will be dealing with hazardous substances – they might be not only poisonous but also flammable! The Bosh BME680 sensor This…

SDS011, ESP8266, BME280, SSD130 and Wemos Relay Shield - Relay ON

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…

Najmniejszy system weryfikacji smogu

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…

PLNOG 18 Warszawa - Domoticz i DIY

PLNOG: The 18th, 19th and 22nd Polish editions – with presentations, both SildeShare and YouTube (Polish language only)

PLNOG is a conference held in Warsaw and Krakow twice a year. This is the place where IT and telco people meet. Last time I spoke about some of my experiences in building small devices, listen if want to (Polish only): During next PLNOG 19 I’m going to talk about SMOG sensor: Big Thank You to all who were present – hope you liked it! Presentation: SMOG w Grafanie (PLONOG 19 w Krakowie) from Lukasz C. Jokiel PLNOG 22, thanks for attendence and comments! PLNOG22…

Power supply for Raspberry Pi, Orange Pi, ESP8266 – XBOX 360 PSU modification

Proper supply of power is a very important part of our SBC (Small Board Computers) projects. Power supplies with too low current efficiency, instability and lack of filtration – often lead to accidental resets, lack of sensor readings or simply unstable behavior of SBCs. One of the solution is to modify the power supply from Microsoft console – XBOX 360. WARNING: We will work with high currents and high voltage, which requires basic knowledge of electrical engineering. The author is not responsible for accidents and…

Raspberry Pi B+ with Neoway GSM M590 module

Raspberry Pi and GSM network- sending SMS, connecting to the Internet (IoT)

This time I’m going to connect to our Raspberry Pi a GSM module. Why? Internet of Things, in short IoT, as it was noted at Krakow’s PLNOG17  by Marcin Aronowski involves and depends on the network which should be easily accessible, and the very essence of IoT is the energy efficiency. Perhaps, he said, 3G will go away but 2G but will still remain. And we do not huge pipes – just enough bandwidth. 2G connection is still the cheapest in the implementation (also due…

Rain/Snow/Water detection system

Domoticz part 6: Water/Rain/Snow/ sensor FC-37 using ESPEasy (digital)

We return today to the simple and quick solutions! The weather station or irrigation/sprinkler system – can’t operate without proper detection of rain, water or even snow. Let’s use the FC-37 sensor (also know as YL-38 or MH-RD, or just similar to the picture) What will you need? rain sensor type FC-37/MH-RD (rain drop/snow sensor) – must come with D0 pin, price around $0.50 to $1.50 ESPEasy working on ESP8266 from the previous entries Installation and configuration The sensor must be connected to the power supply + 3.3V (3V)…
