Did you ever wonder how these cheap weather stations transmit Data?
If you search the web you may find some information where people use RTL SDR TV sticks to decode such data.
My idea was: Why use such power hungry devices that draw a lot of battery if you can go smaller and more efficent.
Thats why I built a small decoder for this cheap weather stations from Bresser.
The idea was to place this decoder out in the wild and transmit the decoded data via Lora to my home.
With this idea I can make my own accurate local weather model with very remote sensors.
You can check wind direction, rain, Heat in remote areas without need for a mobilephone network.
Efficeny is good due to the fact that the microcontroller will sleep the most of the time.
Right now I am in Beta phase. Decoding works, LoRa Transmission works.... time to get a housing and try it out in the wild
