 Post subject: LoRa P2MP sensor data transmission

Hi

Im wanting to make a small project for myself but before I buy the parts from you I have a few questions.

I want to transmit the voltage of a sensor from 2 Arduinos to a master Arduino, via LoRa. The Master Arduino must relay these to voltage inputs as a voltage output.

Is this possible with an Arduino and LoRa shield?

Thanks

Hello Bernd,
Yes, it is feasible. You must do a star network configuration. Take a view to our documentation:

Thank you.

If I were to use your 4-20mA board and have a sensor 400m away. Would the board still get a signal from sensor?

Hello Bernd,
With a 4-20mA interface protocol you can rearch up to 900m (theoricaly) but we have never tested this situation with our board.
Regards.
