26 == 1.1 What is D2x-NB NB-IoT Temperature Sensor ==
27
28
29 The Dragino D2x-NB is a (% style="color:blue" %)**NB-IoT Temperature Sensor**(%%) for Internet of Things solution. D2x-NB has 1 ~~ 3 temperature probes. D2x-NB will convert the Temperature reading to upload the sensor data send to IoT platform via NB-IoT network.
30
31 The temperature sensor used in D2x-NB can (% style="color:blue" %)**measure -55°C ~~ 125°C with accuracy ±0.5°C (max ±2.0 °C)**.
32
33 D2x-NB supports (% style="color:blue" %)**temperature alarm feature**(%%), user can set temperature alarm for instant notice. D2x-NB supports Datalog feature, it can save the data when there is no NB-IoT network and uplink when network recover.
34
35 D2x-NB has max 3 probes which measure maximum 3 temperature points.
36
37 D2x-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.
38
39 D2x-NB (% style="color:blue" %)**supports BLE configure and OTA update**(%%) which make user easy to use.
40
41 D2x-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.
42
43 D2x-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
