Streamlined Sensor Data Integration

 

The Dragino RS485-NB serves as a critical link between RS485 or UART sensors and IoT servers, enabling consistent data transmission over the NB-IoT network. It's designed to read sensor data periodically, making it a cornerstone in IoT ecosystems.

Telemetry2U Integration for Enhanced Monitoring: Through Telemetry2U, this converter offers real-time data visualisation on dashboards, instant alerts via email, SMS, and voice calls, and access to historical data. Its ability to support custom payload decoders and downlink commands allows for versatile interfacing with various digital output devices.

Optimised Power Management: The RS485-NB provides both 3.3v and 5v outputs to power external sensors. These outputs are controllable, significantly reducing the system's overall power consumption, a critical feature for energy-efficient operations.

Flexible Connectivity for Diverse Needs: Supporting a range of uplink methods, including MQTT, MQTTs, UDP, and TCP, the RS485-NB is adaptable to different IoT servers. This flexibility caters to varied application requirements, enhancing its utility.

User-Friendly Configuration: Designed with BLE configuration and OTA updates, the converter is straightforward to use, simplifying device management and ensuring users are always up-to-date with the latest software.

Long-Term Reliability: Powered by an 8500mAh Li-SOCI2 battery, the RS485-NB is built for longevity, offering several years of reliable service without frequent battery replacements.

 

 

Choose the 12-Month Subscription with Telstra SIM

 

 

When you select one of the "12-month IoT Platform Subscriptions", we'll handle all necessary configurations for seamless integration into Telemetry2U's IoT platform. If you also ordered a Telstra 500KB NB-IoT SIM card with your device, That'll also be installed and configured prior to shipment. The SIM card is locked to the device and the data capped at 500KB, so there is no chance of any suprise charges.
