Dragino SDI-12-NB SDI-12 to NB-IoT converter

SDI-12-NB is an SDI-12 to NB-IoT converter, developed for the Smart Agriculture solution.

SDI-12 (1200 baud serial digital interface) is asynchronous for smart sensors that monitor environmental data. The SDI-12 protocol is widely used in agricultural sensors and weather stations.

The SDI-12-NB has an SDI-12 interface and supports 12V output to power an external SDI-12 sensor. It can receive environmental data from SDI-12 sensor and send the data via NB-IoT wireless protocol.

The SDI-12-NB supports various uplink methods including MQTT, MQTT, UDP and TCP for different application requirements as well as supporting uplink to different IoT servers.

SDI-12-NB supports BLE configuration and OTA update , which makes it easy for the user to use.

The SDI-12-NB is powered by Li-SOCI2 battery with a capacity of 8500 mAh , designed for long-term use of up to several years.

The SDI-12-NB has an optional built-in SIM card and a default IoT server connection version. Due to this, it works with a simple configuration.
