Your Houseplants Really Can Impact Indoor Air Quality, Depending on The Pollutant
Indoor air quality can be significantly improved by houseplants, new research has shown – specifically in terms of removing nitrogen dioxide (NO2) from the air, a pollutant created from fuel burning that's been linked to respiratory disease.

Kiss the Ground …by Regenerating the Soil, we Can Completely Stabilize Earth’s Climate

Featuring the world’s leading scientists, experts, farmers, and activists, NASA and NOAA footage, and real-world examples of regenerative agriculture, the film illustrates how the relatively simple solution of drawing down atmospheric carbon into the soil can solve humanity’s greatest challenge…if we don’t give up and we work together.

DIY Open Source Air Quality Sensor Using An e-Ink Display

The core sensor is the SGP40, which detects volatile organic compounds (VOCs) in the air while consuming less than 3 mA (compared to the 48 mA of the previous generation). There’s a temperature, barometric pressure, humidity, and light sensors in the package as well.

Andrew not only designed the sensor but has done a thorough job on the documentation. Check out the GitHub repository of the project for a complete data package covering all aspects of the design, including the weather forecasting app note by John Young (an NXP engineer, not the astronaut).

How to Build Air Quality Analyzer using Arduino and Nova PM Sensor SDS011 to Measure PM2.5 and PM10

An interesting project for measuring indoor air quality as it's worth noting that for many homes the indoor air quality is actually worse than outdoor air pollution. The demonstration here just shows the lighting of a match and how the readings jump up, and then die down again as that pollution disperses.

The sensor uses a laser diode and a photodiode to detect and count particles, while a fan moves air through the system. If you aren’t up on pollution metrics, PM2.5 is a count of very fine particles (under 2.5 microns) and PM10 is a count of particles for 10 microns.

One thing to note is that the sensor has a finite lifespan. The datasheet claims “up to” 8,000 hours. If you ran the sensor continuously that’s not quite a year, so you might want to be judicious about how often you light up the device.
