The Elecrow Lora Shield is a long range transceiver on a Arduino shield form factor and based on Open source library.The Lora Shield allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
Using Hope RF's patented LoRa� modulation technique the Lora Shield can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. They can easily go 2 km line of sight using simple wire antennas, or up to 20 km with directional antennas and settings tweakings. LoRa� also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption .
The RFM95 Shield is an inexpensive and versatile radio module. You can use it to send text or binary data between two or hundreds of modules. It�s perfect for building inexpensive long-range wireless networks for home automation, citizen science, and more.
