my Bluetooth thermometer kind of works in my microwave oven – is this a problem? (lemm.ee)

So I have one of those Bluetooth thermometers for meat and other foods. I heard it wasn’t supposed to work in my oven, because it’s a combination of a regular oven in the microwave. Since microwaves are supposed to be a faraday cage, it was my understanding that no radiation should be able to get out.

On the other hand, Bluetooth sensors are so incredibly sensitive, that my microwave might still be well within safe margins in terms of escaping microwaves.

It’s worth pointing out that the reception on my Bluetooth thermometer doesn’t work very well, but if I hold my mobile phone in certain places near the oven and will shortly catch a signal.

Should I be worried and buy a new oven?

Microwave ovens are enclosed in a cage designed to stop the particular wavelength of radiation they emit. I suspect this has been confused with a Faraday cage.

You mean they are supposed to block exactly the same 2.4Ghz to 2.5Ghz range that both regular consumer microwave ovens and Bluetooth use?
