15 | |||
16 | == 1.1 What is NDS01 NB-IoT Door Sensor == | ||
17 | |||
18 | |||
19 | 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. | ||
20 | |||
21 | Besides open/close event, NDS01 also has an internal temperature and humidity sensor which can detect the temperature and humidity inside the sensor. | ||
22 | |||
23 | **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. | ||
24 | |||
25 | NDS01 is powered by 2 x AAA batteries for long term use. | ||
26 | |||
27 | *The measured temperature is 2~~3 degree higher than the actually environment temperature out of NDS01. | ||

79 | = 2. Use NDS01 to communicate with IoT Server = | ||
80 | |||
81 | == 2.1 How it works == | ||
82 | |||
83 | |||
84 | 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. | ||
85 | |||
86 | The diagram below shows the working flow in default firmware of NDS01: | ||
87 | |||
88 | |||
89 | == 2.2 Configure the NDS01 == | ||
90 | |||
91 | === 2.2.1 Test Requirement === | ||
92 | |||
93 | |||
94 | To use NDS01 in your city, make sure meet below requirements: | ||
95 | |||
96 | * Your local operator has already distributed a NB-IoT Network there. | ||
97 | * The local NB-IoT network used the band that NDS01 supports. | ||
98 | * Your operator is able to distribute the data received in their NB-IoT network to your IoT server. | ||
99 | |||
100 | 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. | ||
101 | |||

104 | |||
105 | |||
106 | === 2.2.1 Insert SIM card === | ||
107 | |||
108 | |||
109 | Insert the NB-IoT Card get from your provider. | ||
110 | |||
111 | User need to take out the NB-IoT module and insert the SIM card like below: | ||
112 | |||
113 | |||
114 | [[image:1668224846067-276.png]] | ||
115 | |||
116 | |||
117 | === 2.2.3 Configure NDS01 === | ||
118 | |||
119 | |||
120 | 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. | ||
