The Arduino LoRa Transceiver Shield is a long range Arduino LoRa shield, based on an open-source library. LoRa Shielding allows the user to send data and reach very long distances at very low data rates. It offers ultra-long range spectrum communication with high interference immunity while minimizing current consumption.
RFM95W-based LoRa Shield targets professional wireless sensor network applications such as irrigation systems, smart meters, smart cities, smartphone detection, building automation, and so on.
