Hi!
I was wondering if it is legal to use a wireles bluetooth tranceiver found on ebay for my thermometer hobby project.
Something like this:

Also a 433MHz or 868MHz SDRs for same purpose. Something like:

Probably these devices will be transmitting every 5s a small burst of data.

I live in Greece.

 

I think the Bluetooth transceivers should be legal to use in Greece as Bluetooth is used in most PC. and tablets. Bluetooth only has quite a short range. I do not know if the 433 Mhz and 868 Mhz devices are legal in Greece. When I saw you use the "SDR" acronym I assumed you meant software defined radio but you must be using in some other context. (What is it out of interest.) If the HC-12 units are legal in Greece then I would recommend them. They have a much greater range than bluetooth. I use them myself for remote temperature and humidity sensors with DHT22 sensors and for remote voltage and current sensing with INA219 modules. (All of these use a PIC12F1840 to convert the data to ASCII text messages.)

Les,

I meant SRDs - short range devices. A typo.
I'll check for greece.
Thanks
