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.

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.

By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8

747

748

User can use below commands to change the (% style="color:blue" %)**uplink interval**.

749

== 2.5 Multi-Samplings and One uplink ==

756

757

758

To save battery life, DS03A-NB will sample Water Flow data every 15 minutes and send one uplink every 2 hours. So each uplink it will include 8 stored data + 1 real-time data. They are defined by:

759

760

* (% style="color:#037691" %)**AT+TR=900** (%%) ~/~/ The unit is seconds, and the default is to record data once every 900 seconds (15 minutes, the minimum can be set to 180 seconds)
