Fewer premature babies born since Covid-19 lockdown
Air pollution is something to be taken <i>very</i> seriously,<p>Regarding that (and since we are hackers here), I bought myself one of these last year:<p><a href="https:&#x2F;&#x2F;m5stack.com&#x2F;products&#x2F;pm-2-5-sensor-usb-power-sht20" rel="nofollow">https:&#x2F;&#x2F;m5stack.com&#x2F;products&#x2F;pm-2-5-sensor-usb-power-sht20</a><p>Pretty affordable and it works really well, readings match another device I have which was much more costly.<p>Since then I turn it on from time to time, I live in an apartment near a highway, I am impressed by:<p>How much air quality changes between days, during the day and depending on whether there&#x27;s traffic or not,<p>how much it changes due to household activities (cooking, cleaning).<p>and how it changes when someone is smoking, even outside of my unit.<p>Thanks to this I have developed a routine of opening&#x2F;closing windows at certain times that allows me to improve the average air quality inside my place. If I had the time (and some actuators) I could probably automate that, that would be cool yeah :D.<p>I highly recommend getting one of these or a similar sensor. Also, I&#x27;m looking to find something similar but capable of measuring CO and CO2, if anyone knows let me know.
