7 == **1.1 ​**What is CPN01 **NB-IOT** Pulse/Contact Sensor ==
8
9 The Dragino CPL01 is a **NB-IOT Contact Sensor**. It detects open/close status and uplink to IoT server via LoRaWAN network. user can see the dry contact status, open time, open counts in the IoT Server.
10
11 The CPL01 will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculate last open duration. User can also disable the uplink for each open/close event, instead, device can count each open event and uplink periodically.
12
13 CPL01 has the open alarm feature, user can set this feature so device will send Alarm if the contact has been open for a certain time.
14
15 CPL01 is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.
16
17 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.
18 \\CPN01 supports different uplink methods include **TCP,MQTT,UDP and CoAP  **for different application requirement.
19 \\CPN01 is powered by  **8500mAh Li-SOCI2 battery**, It is designed for long term use up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)
20 \\To use CPN01, user needs to check if there is NB-IoT coverage in local area and with the bands CPN01 supports. If the local operate support it, user needs to get a **NB-IoT SIM card** from local operator and install CPN01 to get NB-IoT network connection

115 = **2.  Use CPN01 to communicate with IoT Server** =
116
117 == **2.1  How it works** ==
118
119 The CPN01 is equipped with a NB-IoT module, the pre-loaded firmware in CPN01 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 CPN01.
120
121 The diagram below shows the working flow in default firmware of CPN01:
122
123 [[image:image-20221021110615-5.png]]
124
125 == **2.2 ​ Configure the CPN01** ==
126
127 === **2.2.1 Test Requirement** ===
128
129 To use CPN01 in your city, make sure meet below requirements:
130
131 * Your local operator has already distributed a NB-IoT Network there.
132 * The local NB-IoT network used the band that CPN01 supports.
133 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
134
135 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The CPN01 will use CoAP(120.24.4.116:5683) or raw UDP(120.24.4.116:5601) or MQTT(120.24.4.116:1883)or TCP(120.24.4.116:5600)protocol to send data to the test server

497 == **2.16  ​Battery Analysis** ==
498
499 === **2.16.1  ​Battery Type** ===
500
501 The CPN01 battery is a combination of an 8500mAh Li/SOCI2 Battery and a Super Capacitor. The battery is none-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.
502
503 The battery is designed to last for several years depends on the actually use environment and update interval. 
504
505 The battery related documents as below:

512
513 === **2.16.2  Power consumption Analyze** ===
514
515 Dragino battery powered product are all runs in Low Power mode. We have an update battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit interval.
516
517 Instruction to use as below:
518
519 **Step 1:  **Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from: [[https:~~/~~/www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]]
520
521 **Step 2: ** Open it and choose
522
523 * Product Model
524 * Uplink Interval
525 * Working Mode
526
527 And the Life expectation in difference case will be shown on the right.

530
531 === **2.16.3  ​Battery Note** ===
532
533 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.
534
535 === **2.16.4  Replace the battery** ===
536
537 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).
