Long range wireless temperature sensor

Mon Jun 24, 2019 7:23 pm

Can anyone give me info on a xmtr/rcvr pair that will let me monitor outside temp and possibly humidity and be able to have some data output on the rcvr that I can use to write some code for a PI? Some sort of module thing that's maybe a transceiver or an off the shelf premade unit? Better because I'd like something FCC approved. Needs to be long range 1/2 mile or more. -- thanks

For that distance I would look at LoRa or Sigfox links but you may find that a GPRS card and low volume data sim may work out cheaper.

I know Sigfox have dedicated devices that are basically the sensor and transmitter in one unit but they should not be hard to replicate the functionality with a Zero.

I’ve had experience with WiFi extenders but in the U.K. they needed licensing and cost a bomb (still cheaper than a new line to site though).
