83.5	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.
1.1	30
83.5	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).
1.1	32
83.16	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.
1.1	34
83.3	35	D2x-NB has max 3 probes which measure maximum 3 temperature points.
1.1	36
83.5	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.
1.1	38
83.5	39	D2x-NB (% style="color:blue" %)supports BLE configure and OTA update(%%) which make user easy to use.
1.1	40
83.23	41	D2x-NB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long-term use up to several years.
82.37	42
83.3	43	D2x-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
