18 == 1.1 What is DS03A-NB NB-IoT Door Sensor ==
19
20
21 The Dragino DS03A-NB is a (% style="color:blue" %) **NB-IoT Door Sensor**(%%) for Internet of Things solution. It (% style="color:blue" %)**detects door open/close status**(%%) and uplinks to IoT server via NB-IoT network. user can see the door status, open duration, open counts in the IoT Server.
22
23 The DS03A-NB will send periodically data every 2 hours as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, DS03A-NB can count each open event and uplink periodically.
24
25 DS03A-NB supports (% style="color:blue" %)**Datalog Feature,** (%%)it can save the data when there is no NB-IoT network and uplink when network recover.
26
27 DS03A-NB has the (% style="color:blue" %)**Open Alarm Feature**,(%%) user can set this feature so the device will send an alarm if the door has been open for a certain time.
28
29 DS03A-NB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures
30
31 DS03A-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.
32
33 DS03A-NB (% style="color:blue" %)**supports BLE configure **(%%)and(% style="color:blue" %)** OTA update**(%%) which make user easy to use.
34
35 DS03A-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.
36
37 DS03A-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
