The GP LoRa Farm Node is a ready-to-use telemetry device
in agricultural applications. It has temperature measurement sensors
environment, ambient humidity, atmospheric pressure, temperature
soil and soil moisture. The device communicates with the nearest
Gateway where it "sends" its measurement data. Powered
from a battery that gives it about 2.5 years of autonomy, doesn't it?
some action is required by its owner for a long period of time, beyond installation.

The lora Shield based on RFM95W targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.
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. 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.
These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The lora Shield deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
