Lora sx1276 915MHZ

LoRa achieves something neither WiFi nor Bluetooth can: kilometres of range at very low power, by trading data rate for sensitivity. That makes it the right technology for scattered field sensors, agricultural monitoring and remote telemetry where nodes must run for months on a battery and report small amounts of data occasionally. It is not for streaming or bulk transfer. One important point before ordering: this is the 915 MHz variant, which is the Americas band. Europe, the Middle East and most of Africa use 868 MHz, so confirm the correct band for your region and local regulations. Kilometres of range at very low power consumption; Runs for months on a battery in sensor nodes; Penetrates buildings and terrain far better than 2.4 GHz; Standard SPI interface, works with RadioHead and LoRa libraries
