18 == 1.1 ​ What is NDS03A NB-IoT Open/Close Door Sensor ==
19
20
21 (((
22 The Dragino NDS03A is an (% style="color:blue" %)**Open/Close NB-IoT Door Sensor**(%%). It detects door (% style="color:blue" %)**open/close status**(%%) and (% style="color:blue" %)**uplinks**(%%) to IoT server via NB-IoT network. NDS03A can connect two door sensors. user can see the door status, open duration, open counts in the IoT Server.
23 )))
24
25 (((
26 The NDS03A will send periodically data (% style="color:blue" %)**every 4 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, NDS03A can count each open event and uplink periodically.
27 )))
28
29 (((
30 NDS03A has a (% style="color:blue" %)**Datalog feature**(%%), it will record the open/close event and the user can retrieve the history from NB-IoT.
31 )))
32
33 (((
34 NDS03A 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.
35 )))
36
37 (((
38 NDS03A is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.
39 )))
40
41 (((
42 NarrowBand-Internet of Things (NB-IoT) is a (% style="color:blue" %)**standards-based low power wide area (LPWA) technologyTCP, MQTT, UDP, and CoAP**(%%) for different application requirements.
43 )))
44
45 (((
46 NDS03A is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long-term use of up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)
47 )))
48
49 (((
50 To use NDS03A, user needs to check if there is NB-IoT coverage in the field and with the Nb-IoT bands that NDS03A supports. If local operator support it, user needs to get a (% style="color:blue" %)**NB-IoT SIM card**(%%) from the operator and install into NDS03A to get NB-IoT network connection.

174 == 2.1  How it works ==
175
176
177 In this user case, the NDS03A is installed on the door edge to detect the open/close event and send the status to the NB-IoT server. The NB-IoT network will forward this value to IoT server via the protocol defined by NDS03A.
178
179 The diagram below shows the working flow in the default firmware of NDS03A:

186
187 === 2.2.1 Test Requirement ===
188
189
190 To use NDS03A in your city, make sure to meet below requirements:
191
192 * Your local operator has already distributed an NB-IoT Network.
193 * The local NB-IoT network used the band that NDS03A supports.
194 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
195
196 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NDS03A will use** (% style="color:red" %)CoAP(120.24.4.116:5683)(%%)** or raw (% style="color:red" %)**UDP(120.24.4.116:5601) **(%%)or (% style="color:red" %)**MQTT(120.24.4.116:1883) **(%%)or (% style="color:red" %)**TCP(120.24.4.116:5600)protocol**(%%) to send data to the test server.

484
485 User can set calculate flag to 1 for meter 1~~50 and 2 for meter 51 ~~ 100, So IoT Server can use this field for calculation.

700 The CPN01 battery is a combination of an 8500mAh Li/SOCI2 Battery and a Super Capacitor. The battery is non-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
701
702 The battery is designed to last for several years depends on the actual use environment and update interval.

739 === 2.16.3  ​Battery Note ===
740
741
742 The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.
743
744
745
746 === 2.16.4  Replace the battery ===
747
748
749 The default battery pack of CPN01 includes a ER26500 plus super capacitor. If user can't find this pack locally, they can find ER26500 or equivalence without the SPC1520 capacitor, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes).
