SDI-12-NB SDI-12 to NB-IoT Converter designed for IOT Agriculture solution

The Dragino SDI-12-NB is an SDI-12 to NB-IoT Converter designed for Smart Agriculture solutions.

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 sensors and Weather Station sensors.

SDI-12-NB has an SDI-12 interface and supports 12v output to power the external SDI-12 sensor. It can get the environment data from the SDI-12 sensor and send out the data via NB-IoT wireless protocol.

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

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

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

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