If you leave windows open, yes. 😉
It's European network of labs.
Based on wrong data from "amateur" kind of meters and imported to seller network then pubilshed, my city (and some others) was declared "most polluted city in EU" which was totally wrong

In NL they placed some probes right over the sewage collectors, and then complained, that the ammoniac level is too high, hence the car speed should be reduced.
Anyway, back to the device. It can be calibrated, it can draw graphs, it does not have any WiFi/BT/USB data connectivity (the smartphone pictures on the Ali page are misleading, however it's clearly said on the description, that USB-C is for charging only), it's got a silent fan to pull the air through. At least it's quite good for comparison and showing the dynamics. So far, satisfied 😊

This thing is really cool and very flexible! Exactly what I was looking for! I have a shelf above my desk, and I needed an arm/boom for holding a phone, microphone, light, loupe, third arm for welding, etc, that can be mounted to that shelf. It works exactly like that. Might be too cumbersome to tune and adjust, but this is the price you pay for the universality.

'sprouting machine'
I grow my sprouts in a Spaten beer stein I stole from Munich Oktoberfest about forty years ago. I'm not proud of that but I don't see why I need to buy a machine to do the job 😊
RE: Various useful things on Ali/eBay/whatever - Like Ra - 05 Dec 2021
The idea of this sprouting machine is circulating warm water, what should speed up sprouting. Looks like they did not send me anything anyway, so I ordered "passive" plastic sprouters to keep things tidy and aesthetic. And yes, currently I'm using whatever piece of glass or ceramic is free 😆

This might a solution for all AA/AAA/9V batteries: USB-charged lithium accumulators. Bonus: 1.5V instead of 1.2V

Very new and very cool thing: Huawei Watch D with built-in sphygmomanometer and ECG sensor. It controls temperature, blood pressure, pulse, oxygenation, heart and artery health, sleep apnoea, and a bunch of other things. It costs a bit, but this thing is rather unique at the moment.

LusyaTechnology Store - interesting shop, which is selling various electronic stuff from electronic boards, through ready to use hifi devices (DACs, Amps, headphones) to Schumann generators. Even if not buying, it's quite intriguing to browse/check what the technical progress can offer.

Any experience with smart temperature/humidity sensors? I'm thinking about wifi tuya temperature sensors
