I am puzzled by this sensor. Everything says "indoor", but it has a 300M wireless range so can it be mounted outdoors or only indoors?

Indoors and up to 300m from the console. That's how I read it.

So you think it can only be used indoors rather than measuring outdoor air quality Freddie?

That's how it reads to me. Is there a part number, then I could check with Ecowitt.

If it's this one
https://www.amazon.co.uk/Ecowitt-Wirele ... B09B3R7387 then in the spec is says this:
Indoor Air Quality Detector: Suitable to use at home, office, car and other indoor testing

That is the one Freddie. Pity I was hoping that I could use it outside as I don't see the point of running it indoors.

It's 300
feet according to the Ecowitt site. Does that make a difference
And the indoor qualifier I think has to do with the USB possibility for power.
As far as I understand it you may just as well use it outside (protected from rain that is) as long as it is on a battery.
Maybe @Phil23 can say something here, he has one.

I've got the outdoor one with a solar panel, but the solar charging stopped working ages ago, probably to do with the rain/wind etc.
Lot's of folk were saying that it needs to be protected from the elements, which defeats the object of a solar panel?!

One of the main features of the WH45 5-in-1 air quality sensor is its CO2 sensor .
Measuring the CO2 concentration outdoor is quite a futile exercise as it is +/- the same most of the time.
It's meant to be an indoor sensor, but of course, if you wish, you can also use it outdoors.
It will need to be well protected against high humidity (as this will affect the PM2.5 and PM10 readings),
it doesn't recharge the batteries like the outdoor PM2.5 sensor (WH41) as it doesn't have an inbuilt solar panel
- you can keep it connected to a USB charger though, but I would seal the connection with some silicone for protection.
