SDI-12-LB LoRaWAN Converter Node 868MHz

The SDI-12-LB LoRaWAN Converter Node is an innovative LoRaWAN solution for smart agriculture, which allows 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. Utilizing LoRa wireless technology, the SDI-12-LB has the ability to send data over extremely long distances at low data rates, ensuring comprehensive coverage even in remote agricultural areas. Powered by an 8500mAh Li-SOCI2 battery or a combination of solar power and Li-Ion battery, the converter is designed for long-term use of up to five years without the need for battery replacement. Each SDI-12-LB also comes pre-loaded with unique keys for LoRaWAN registration, allowing easy setup and automatic connection after power-on.

Each sensor comes pre-loaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically establishes a connection upon power-on if network coverage is available.
