SDI-12-LB LoRaWAN Converter Node 868MHz

The SDI-12-LB LoRaWAN Converter Node is an innovative LoRaWAN solution for smart agriculture, enabling seamless integration of SDI-12 sensors into the LoRaWAN network. This converter unit is specifically designed to collect environmental data from SDI-12 compatible sensors and transmit it via the LoRaWAN protocol. By utilizing LoRa wireless technology, the SDI-12-LB offers the ability to send data over extremely long distances at low data rates, providing comprehensive coverage even in remote agricultural areas. Powered by an 8500mAh Li-SOCI2 battery or a combination of solar energy and Li-Ion battery, the converter is designed for long-term use of up to five years without requiring a battery change. Each SDI-12-LB is also preloaded with unique keys for LoRaWAN registration, enabling easy setup and automatic connection upon power-up.

Each sensor is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the sensor automatically connects after power-up when network coverage is available.
