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.
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.
The components of the device are as follows:
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:
The data can be sent to any other servers or maps.
The visual interpretation of the data obtained by the sensors can be presented as follows:
Interactive information from air quality stations. Analytics, automatic notification about excesses.
Dedicated web page with 48 hours measurement log, download of the archive of station data, etc.
Allowing a user to subscribe to notifications based on a variety of different parameters including geo-location, PM level, etc.
The hardware controller is using open-source software available at GitHub.
Each device is automatically updated once the new updates are available.
Our server also automatically publishes data at https://api.saveecobot.com/output.json
