Versatile Connectivity and Long-Term Reliability The sensor node supports various uplink methods including MQTT, MQTTs, UDP, and TCP, catering to diverse application needs. Its 8500mAh Li-SOCI2 battery ensures long-term operation, and the optional built-in SIM card simplifies connectivity.

Enhanced with Telemetry2U Integration Integrating with Telemetry2U, the SN50v3-NB elevates its functionality. It offers instant notifications, the capability to create custom payload decoders, and the option to interface with a myriad of devices. Users can visualise and analyse historical data, harnessing the power of IoT for informed decision-making.



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.
