I want my own station!


Brief overview

The outdoor air quality monitoring station allows measuring concentration of fine particulate matters of 2.5 and 10 microns fractions in the air (so-called PM 2.5 and PM 10 particles). An integrated temperature-humidity-pressure sensor automatically adjusts the information obtained depending on the weather conditions. The heating module allows obtaining reliable information under different weather conditions such as fog, rain, and negative outside temperatures.

Approximate price range:
$50-70 (depending on the version, shipping conditions, and local customs)
58x115x125 mm (main box)
300 g

Compact and affordable instruments for measuring atmospheric air basics are a worldwide trend. General public and researchers around the world have realized that it makes more sense to obtain rather not always perfectly accurate, but large data sets from thousands of different points than to have even very precise and expensive monitoring stations, but only in a few points. Due to a low price of such household sensors, many people can afford them.

The fine dust of the PM10 and PM2.5 fractions cause a variety of cardiovascular, allergic and respiratory diseases. This type of pollution is one of the most dangerous for the human being. That is why our sensors measure exactly PM10 and PM2.5 pollution level.

Activists from Sensor.Community (Stuttgart, Germany) and from the company Nettigo (Warsaw, Poland) have already made thousands of devices based on similar technology and spread them all over the world. We took their idea as a reference and made it even better. Here and here you can find some laboratory studies proving the adequacy of the data obtained from such devices.

Technical details

The components of the device are as follows:

  • SDS011 – PM sensor
  • Wemos D1 mini V2 Pro – main controller
  • BME280 – temperature, humidity and pressure sensor
  • Plastic housing
  • Power supply
  • Automated air heating camera

The device conducts measurements every 145 seconds (can be changed in the configuration) and sends the data over the Wi-Fi directly to the following online resources:

  1. Aqicn
  2. OpenSenseMap
  3. SaveEcoMap
  4. Sensor.Community
  5. Luftdaten
  6. Madavi.de Archive

The data can be sent to any other servers or maps.

The visual interpretation of the data

The visual interpretation of the data obtained by the sensors can be presented as follows:

Open data, open-source, and open-hardware

The hardware controller is using open-source software available at GitHub.

The original version of the hardware is available as open-hardware at Nettigo Air Monior and at Sensor Kits.

Each device is automatically updated once the new updates are available.

Our server also automatically publishes data at https://api.saveecobot.com/output.json

Anyone can use it provided that the hyperlink on SaveEcoBot is indicated.
