17 +== 1.1 ​What is NDS01 NB-IoT Door Sensor ==
18 +
19 +
20 +The Dragino NDS01 is a NB-IOT Door Sensor for Internet of Things solution. It is used to detect the open/close event for door and uplink the event to IoT server via NB-IoT network.
21 +
22 +Besides open/close event, NDS01 also has an internal temperature and humidity sensor which can detect the temperature and humidity inside the sensor.
23 +
24 +**NarrowBand-Internet of Things (NB-IoT)** is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
25 +
26 +NDS01 is powered by 2 x AAA batteries for long term use.
27 +
28 +*The measured temperature is 2~~3 degree higher than the actually environment temperature out of NDS01.

87 += 2. Use NDS01 to communicate with IoT Server =
88 +
89 +
90 +== 2.1 How it works ==
91 +
92 +
93 +The NDS01 is equipped with a NB-IoT module, the pre-loaded firmware in NDS01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by NDS01.
94 +
95 +
96 +The diagram below shows the working flow in default firmware of NDS01:
97 +
98 +
99 +
100 +
101 +== 2.2 Configure the NDS01 ==
102 +
103 +=== 2.2.1 Test Requirement ===
104 +
105 +
106 +To use NDS01 in your city, make sure meet below requirements:
107 +
108 +* Your local operator has already distributed a NB-IoT Network there.
109 +* The local NB-IoT network used the band that NDS01 supports.
110 +* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
111 +
112 +Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NDS01 will use UDP(120.24.4.116:5601) or TCP(120.24.4.116:5600)protocol to send data to IoT server.

115 +
116 +
117 +
118 +=== 2.2.1 Insert SIM card ===
119 +
120 +Insert the NB-IoT Card get from your provider.
121 +
122 +
123 +User need to take out the NB-IoT module and insert the SIM card like below:
124 +
125 +
126 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image003.png]]
127 +
128 +
129 +=== 2.2.3 Configure NDS01 ===
130 +
131 +User need to configure NDS01 via serial port to set the **Server Address** / **Uplink Topic** to define where and how-to uplink packets. NDS01 support AT Commands, user can use a USB to TTL adapter to connect to NDS01 and use AT Commands to configure it, NDS01 needs to be in the wake-up state when using AT commands,as below.
