DRAGINO SDI-12 to NB-IoT Converter
DRAGINO SDI-12 to NB-IoT Converter is an SDI-12 to NB-IoT converter designed to collect data from SDI-12 environmental, agricultural and weather station sensors and transmit the information wirelessly. It provides controllable 3.3 V, 5 V and 12 V outputs for external sensors, supports multiple sampling with a single uplink and offers MQTT, MQTTS, TCP and UDP communication options. Bluetooth v5.1 configuration and OTA firmware updates simplify device management.
The DRAGINO SDI-12 to NB-IoT Converter is designed to bridge SDI-12 environmental sensors and NB-IoT wireless connectivity. SDI-12 is an asynchronous serial communication protocol commonly used with agricultural and weather station sensors. The converter reads data from connected SDI-12 sensors and sends the collected information over an NB-IoT network.
The unit provides controllable 3.3 V, 5 V and 12 V outputs for powering external sensors. It can perform multiple sensor samples before sending a single uplink, helping support monitoring configurations where measurements are collected at intervals and transmitted periodically.
How it works
- Connect a compatible SDI-12 sensor to the converter.
- The converter communicates with the sensor using the SDI-12 protocol and collects its measurement data.
- The connected sensor can be powered through the converter's controllable 3.3 V, 5 V or 12 V output.
- Measurements can be sampled multiple times before being sent in an uplink.
- Data can be transmitted over NB-IoT using MQTT, MQTTS, TCP or UDP.
- Bluetooth v5.1 can be used for remote configuration and firmware updates.
