7
8 == **1.1 ​**What is CPN01 **NB-IoT** Pulse/Contact Sensor ==
9
10 The Dragino CPN01 is an (% style="color:blue" %)**NB-IoT Dry Contact Sensor**(%%). It detects open/close status and uplinks the info to IoT server via NB-IoT network. User can see the (% style="color:blue" %)**dry contact status, open time, and open counts**(%%) in the IoT Server.
11
12 The CPN01 will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculates the last open duration. Users can also disable the uplink for each Open/Close event, instead, device can count each open event and uplink periodically.
13
14 CPN01 has** (% style="color:blue" %)Open-Alarm feature(%%)**, user can set this feature so CPN01 will send an alarm if the contact has been open exceeds a certain time.
15
16 CPN01 is designed for outdoor use. It has a weatherproof enclosure and industrial-level battery to work in low to high temperatures.
17
18 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.
19 \\CPN01 supports different uplink methods including (% style="color:blue" %)**TCP, MQTT, UDP, and CoAP**(%%) for different application requirements.
20 \\CPN01 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)
21 \\To use CPN01, user needs to check if there is NB-IoT coverage in the field and with the Nb-IoT bands that CPN01 supports. If local operator support it, user needs to get a (% style="color:blue" %)**NB-IoT SIM card**(%%) from the operator and install into CPN01 to get NB-IoT network connection.

515 == **2.16  ​Battery Analysis** ==
516
517 === **2.16.1  ​Battery Type** ===
518
519 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.
520
521 The battery is designed to last for several years depends on the actually use environment and update interval. 
522
523 The battery related documents as below:

531 === **2.16.2  Power consumption Analyze** ===
532
533 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.
534
535 Instruction to use as below:
536
537 **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/]]
538
539 **Step 2: ** Open it and choose
540
541 * Product Model
542 * Uplink Interval
543 * Working Mode
544
545 And the Life expectation in difference case will be shown on the right.

548
549 === **2.16.3  ​Battery Note** ===
550
551 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.
552
553 === **2.16.4  Replace the battery** ===
554
555 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).
