  • Page 2: Introduction

    1.1 What is D2x-LB LoRaWAN Temperature Sensor The Dragino D2x-LB is a LoRaWAN Temperature Sensor for Internet of Things solution. D2x-LB has 1 ~ 3 temperature probes. D2x-LB will convert the Temperature rea to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.

    Deep Sleep Mode: Sensor doesn't have any LoRaWAN activate. This mode is used for storage and shipping to save battery life. Working Mode: In this mode, Sensor will work as LoRaWAN Sensor to Join LoRaWAN network and send out sensor data to server. Between each sampling/tx/rx periodi sensor will be in IDLE mode), in IDLE mode, sensor has the same power consumption as Deep Sleep mode.
