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.
We don’t have enough experience with the SEN5x yet to give an opinion but it’s definitely a good sensor.
It might be better than the Plantower but on the other hand we know the Plantower really well now after 10s of thousands of units going through our test chamber. This allows us to tweak the Plantower to really good performance.
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?
