he Dragino SDI-12-LB is a SDI-12 to LoRaWAN Converter designed for Smart Agriculture solution. It turns your exisitng SDI-12 device into LoRawan communication.

SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous serial communications protocol for intelligent sensors that monitor environment data. SDI-12 protocol is widely used in Agriculture sensor and Weather Station sensors.

SDI-12-LB has SDI-12 interface and support 12v output to power external SDI-12 sensor. It can get the environment data from SDI-12 sensor and sends out the data via LoRaWAN wireless protocol.

The LoRa wireless technology used in SDI-12-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

SDI-12-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each SDI-12-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here.
