“Portable Air Quality Monitoring Station Based on ESP8266 - AiryFi #Arduino @Arduino
Air is the substance we inhale. It’s around 78 percent nitrogen, 21% oxygen, and 1% argon, plus various ‘other’ bits and pieces, many of which have been blasted out by people and their associated gear. Although carbon dioxide is an apparent pollutant that contributes to climate change, there are other factors to consider for human health, such as particulate matter. This is only very minute particles such as soot and smog. They’re divided into two categories based on particle size: those less than 2.5 microns in diameter (PM2.5) and those between 10 and 2.5 microns in width (PM10). Respiratory sickness, heart disease, and lung cancer have all been related to this pollution.
Obviously, this is crucial information to have, but we have very little data on it in the United Kingdom. While most big cities have official sensors, the impacts may be quite localised near busy routes and confined in valleys. What effect does your neighborhood’s makeup have on air quality? We set out to track our surroundings to discover how concerned we should be about the air quality in our neighbourhood.
Jyoti has released AiryFi, an ESP8266-based air quality monitoring station featuring an inbuilt PMSA003 laser dust sensor and a BME280 humidity sensor. AiryFi is an open-source portable Air Quality monitoring station that measures the quantity and mass of suspended particulate matter (PM1.0, PM2.5, and PM10) per unit volume in the air.
AiryFi allows you to collect detailed information on the mass and quantity of suspended particulates in the air, as well as a humidity sensor that measures relative humidity, barometric pressure, and ambient temperature. You can also share your data to the cloud using the onboard ESP8266, which comes pre-programmed with an AT command set firmware, allowing you to connect it to your Arduino device using C++ and you can see the output on the onboard 1.14” TFT display.”
