We are going to evaluate LoraServer solution. So we need small compatible environment for testing. Sensor, gateway and LoraServer. LoRa server is installed and ready. Can you recommend sensor (e.d. smoke detector or similar) and gateway to create "plug and play demo lab.
Thank yu in advance,
Basic RF95W + arduino : works (~40€)
RN2483 + arduino : not tested (~40€)
TTN node : not recommanded (mine is bricked) (60€ if I remember)
