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?

    You could get a cheap usb a to c 2.0 cable, cut it and extend the wires with some 4 conductor J-YStY cable or what ever is common where you live. The sensor probably doesnt use enough power to cause a significant voltage drop.

      You can buy long USB C cables, just wondering if that’s a good option. Someone else mentioned quite a drop in power delivery with a long cable so I’m thinking POE with a USB adapter might be the best option.

        Voltage drop probably isn’t a problem here, because your sensor draws verry little power. If you can get POE for cheap then thats a better option.
