Wished IKEA didn't put the pads so close to the surface mounted components ... But we're all done soldering the UART Port! 🎉
@rastinza Thanks for the tip! Will try that 👍

@lupyuen In my city there are sensors to measure the quality of the air, and they publish the data online daily.
You could go nearby the area of one of such sensors, write down the reading of yours and wait for them to publish the data.
Do this a few times and you should see if it works decently.
@rastinza Good question ... I'll need an expensive sensor I guess 🤔
@rastinza It's just a consumer grade sensor I guess? After I hook up the UART port to get the raw readings, let's see how accurate they are

@lupyuen Does this make any sense?
I looked at similar sensors, and just the sensor is way more expensive than the full ikea thing.
Since it's so cheap I guess reliability is extremely low and probably useless.
Ok, Static Light Scattering is cheap, but you still need a laser and some computing power.
Moreover I guess it should be calibrated, as I doubt the instrument can retain calibration after manufacturing and shipping.
@amerika Thanks I just trimmed them even shorter, might increase the sensitivity on my fingertips 🤔
