20211103· An indoor air quality monitor with a radon sensor can provide faster results by monitoring levels in real time. Currently, the Airthings Wave is the only monitor in our guide with this capability.

air quality sensors The cost of running a building’s ventilation system can account for as much as 30% of its total running costs. The easiest way to save costs is to reduce the length of time a ventilation system operates, but this has to be balanced against the comfort of people who use the building. Ventilation systems controlled by demand are the most effective at maintaining good levels ...

20180703· The air sensor itself was pretty sensitive to local air quality fluctuations; if I fired up the meat smoker, I’d get an alert. Overall the system was fairly stable, but I did run into some issues where data wasn’t sent to the HTTPTrap at certain times. As a former WiFi firmware engineer, I decided to use tcpdump to look at the traffic directly. To do this, I had to get a host between the ...
