Hahah. Thanks for calling me!

We actually have a sample of the Bosch in our office but haven’t come along to test it yet. Maybe with this call, I will get our team onto it.

The form factor has pros and cons in my opinion. The size and lower energy consumption definitely opens new applications but the problem is that it needs a clear field of view to do the measurements.

This could in turn restrict the applicability, eg as a wearable sensor.

In general I think it’s great to see innovations in the PM sensor field but often minimizations go on costs of accuracy.

We saw that for example with the Sensirion photo acoustic CO2 SCD4x sensor that is tiny but needs more black box algorithms to compensate for certain environmental conditions that then limits the range of applications.

Interesting points - I wasn't aware of the accuracy tradeoffs with smaller sensors, though as an engineer I should probably have anticipated it.

I've been messing around with air quality measurement for a while but haven't got anything for the day to day yet.

Been a long time admirer of the Airgradient project. What are your thoughts on the SEN5x Vs Plantower PM sensors?

I was looking at Radon sensors the other day. FWIU it isn't possible to detect radon with even a PM 2.5 sensor.

I bought a 10-in-1 air quality sensor with USB-C, and it won't do USB-C PD.

Batteries for when the power is out make sense.

Which air quality sensor integrates the most sensors of all?

Does the "Everything Presence One" and (hopefully) upcoming Pro model fall under things you review? Any thoughts on how it stacks up for a smart home device?
