RuuviTag Pro sensor location

I wanted to double check where the RuuviTag Pro sensor actually picks up its readings from. Is it just sensing temperature from the top where the hole is or is there any temp sensing from the bottom of the Tag. I’m trying to determine the best placement when I mount it.


Hi @Qurius ,

Thanks for your message.

RuuviTag sensors’ antenna is positioned so that the signal is slightly stronger upwards from the top cover. The hole covered by Goretex sticker is used to enable RuuviTag to get reliable humidity readings from its surroundings while inside the protective cover.

More tips for improving signal strength can be found here:

I hope this helps!

RuuviTag and RuuviTag Pro both have temperature sensors on their circuit boards. Therefore, the devices in practice measure their own internal temperature. Here is an article about it:
