How do I run power to a USB-C powered sensor? (lemmy.nz)

I'm just bought an Airgradient air quality sensor (actually two, an indoor and an outdoor).

I want to mount the outdoor one but it needs a USB-C power supply. I can run a cable but power isn't exactly close. Do I somehow find a 10m USB-C cable and run it through the roof to the sensor that I mount on the side of the house? What's a normal way of getting USB-C power to an area far away from the closest power point?

Honestly, I would run a normal power cord out there and mount the power point and power converter into an outdoor enclosure.

That way in the future if you change the unit you have a 240/110 outlet there for whatever you need.

I was hoping to avoid needing an electrician!

You shouldn't need a sparkie unless you are adding stuff to the fuse box. I was thinking more of running a cable from the closest wall outlet to the outdoor area.

Ah I see what you mean. I don't really want to use a wall outlet unless I have to. The thing comes with a 4m cable that I could probably run out a window, but I want it all nice and tidy looking. I already have a bunch of network cables running POE to various things going through the ceiling cavity so was planning on mounting it high on the outside wall and running the cable up through one of the eaves and back to my garage setup where everything plugs in.

Someone suggested a POE RJ45 to USB adapter, and that seemed like it would work well with the rest of my setup.
