DS03A-NB -- NB-IoT Door Sensor User Manual

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.
