This example shows how the AVR64DD32 can be used to create a LoRaWAN end node that monitors temperature, humidity, barometric pressure, and soil moisture and transmits that data every three minutes to an application via The Things Network (TTN). The node can be placed anywhere between ten meters and five kilometers from a LoRaWAN gateway in urban environments, but the range is wider for suburban locations. The design demonstrates how an end node, even at long range, can be configured to consume very low power/have long battery life, while securely moving valuable data. This design can be scaled easily to enable the capture of soil variability data by placing additional nodes throughout an agricultural plot without the need to add additional gateways or infrastructure.
