Airborne Particle Monitoring, The BIG Approach
Airborne micro particles generally is a vital well being hazard in a workshop, and thus it’s necessary to keep up a excessive normal of air flow. But monitoring their focus can also be necessary, and thus there exists a spread of sensors to assist hold you protected. [WeSpeakEnglish] has taken this concept to the MAX, with a PM2.5 sensor that drives a really massive wall mounted show. You’ll by no means be unsure what the extent is now!
The standout function of this factor is a large addressable LED seven phase show PCB, upon the again of which sits a tiny Seeed Studio Xiao board to which the particle sensor is attached. The software program shows the particle rely, and handily modifications the color because the quantity creeps upwards. Meanwhile do you have to want to log the readings, the USB exposes a serial port upon which they’re positioned.
We can see it is a helpful venture for wherever that’s more likely to have a excessive particle rely, but it surely’s price noting additionally that a big 7-segment show with an ESP32 board connected might have loads of different makes use of. Meanwhile it is a properly completed air high quality monitor, however it’s certainly not the first we’ve seen.
