The Dragino SDI-12-NB is a SDI-12 to NB-IoT Converter designed for Smart Agriculture solution.

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-NB 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 NB-IoT wireless protocol.

SDI-12-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

SDI-12-NB supports BLE configure and OTA update which make user easy to use.

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

SDI-12-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
