Some links on measuring CO2 and Volatile Organic Compounds in the air

Posted by jpluimers on 2023/05/02

Some links on measuring these:

I was triggered by some messages in a thread:

Note I wrote about Operame before at Source: Operame: Dutch open source CO2 sensor device for indoor usage: shows green/yellow/red for good/okay/bad CO2 ppm levels.

The above also reminded me of [Wayback/Archive] Monitoring my home’s air quality (CO2, PM2.5, Temp/Humidity) with AirGradient’s DIY sensor | Jeff Geerling (Jeff links to his 3D case file and his video [Archive] Your home’s air could be making you sick. Fight back! – YouTube)

That goes with these tweets:

Special cartridges with heat-shrink tubing for dymo and brother label writers

Posted by jpluimers on 2023/04/26

Labeling cables is important, especially when you have a lot of them, and it is tough:

  1. Paper and plastic tables tend to loosen over time.
  2. Numbers or letters you can snap on only work on thicker cables and over time tend to break loose (due to plasticisers evaporating).
  3. Permanent markers are less permanent and fade over time.

Hopefully heat-shrink tubing you can print on with either Dymo or Brother laber writers will outlast 3. At least they won’t loosen like 2. and 1.

So I was glad that [Archive] Jilles🏳️‍🌈 (@jilles_com) / Twitter started a thread, which I tried to help keeping coherent.

Some of the messages:

Measuring environmental aircraft noise (Zelfbouw meetstation voor meten vlieghinder.pdf – Google Drive)

Posted by jpluimers on 2022/10/12

I’ll be following this guideline (or maybe by now already have): Zelfbouw meetstation voor meten vlieghinder.pdf (Google Drive)

This is what I needed:

If you do not have a Raspberry Pi, then you can get it from them as a package for EUR 115 (including case, preinstalled microSD-card, charger and WiFi adapter):[Wayback/Archive.is] Raspberry Pi Zusatzkit zum Komplettpaket Lärm (with configuration manual at [Wayback] Anleitung Raspberry.pdf)
