1.1	19
39.6	20
107.3	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.
1.1	22
107.2	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.
1.1	24
107.10	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.
1.1	26
107.10	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.
107.2	28
107.10	29	DS03A-NB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures
107.2	30
107.10	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.
1.1	32
107.10	33	DS03A-NB (% style="color:blue" %)supports BLE configure (%%)and(% style="color:blue" %) OTA update(%%) which make user easy to use.
1.1	34
107.10	35	DS03A-NB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long-term use up to several years.
1.1	36
107.10	37	DS03A-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
