Bosch’s new BMV080 PM sensor is causing quite a stir in the air quality world and when you see its minuscule 4.4mm x 3mm x 20mm size, it’s easy to understand why. This sensor is fundamentally different from anything we’ve seen before, measuring particles up to 35cm in front of the device rather than within an internal chamber. But does this innovative approach actually work in real-world conditions?

We’ve been putting the BMV080 through a range of form factor testing, exposing it to everything from temperature extremes and strong vibrations to rain simulation and obstruction challenges. Some results were exactly what we expected, but a few genuinely surprised us. The sensor’s unique design creates both exciting possibilities and some notable limitations that anyone considering this technology should understand.
