Two way LoRa mobile transmitters
I’ve always been fascinated by the fact that we can transmit data for a long distance between two devices.
The thing that is fantastic is that it can be done totally free or charge without the use of a mobile subscription.
These two devices allow to send and receive small messages using LoRa technology:
ESP32
RFM95
Battery
Antenna

Take a look at it and if you like it, please subscribe to my channel and look the other vides as well.
