1.5	7
34.1	8	== 1.1 What is CPN01 NB-IoT Pulse/Contact Sensor ==
1.5	9
38.1	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.
1.5	11
38.1	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.
1.5	13
38.1	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.
1.5	15
34.1	16	CPN01 is designed for outdoor use. It has a weatherproof enclosure and industrial-level battery to work in low to high temperatures.
1.5	17
34.1	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.

2.1	115
31.1	116	== 2.1 How it works ==
2.1	117
40.1	118	The CPN01 is equipped with an NB-IoT module, the pre-loaded firmware in CPN01 will get Open/Close Event or Count from sensor and send the value to the NB-IoT network. The NB-IoT network will forward this value to IoT server via the protocol defined by CPN01.
2.1	119
40.1	120	The diagram below shows the working flow in the default firmware of CPN01:

	126
31.1	127	=== 2.2.1 Test Requirement ===
2.1	128
40.1	129	To use CPN01 in your city, make sure to meet below requirements:
2.1	130
40.1	131	* Your local operator has already distributed an NB-IoT Network.
2.1	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
40.1	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.

	348
	349	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.

	394	Examples:
	395
	396	* Set TDC
	397
	398	If the payload=0100003C, it means set the END Node's TDC to 0x00003C=60(S), while type code is 01.

2.1	413
	414	The CPN01 has an internal LED which is to show the status of different state.
	415
	416	* When power on, CPN01 will detect if sensor probe is connected, if probe detected, LED will blink four times. (no blinks in this step is no probe)
	417	* Then the LED will be on for 1 second means device is boot normally.
	418	* After CPN01 join NB-IoT network. The LED will be ON for 3 seconds.

31.1	515	== 2.16 Battery Analysis ==
2.1	516
31.1	517	=== 2.16.1 Battery Type ===
2.1	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:
	524
	525	* [[Battery Dimension>>url:http://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]

2.1	530
31.1	531	=== 2.16.2 Power consumption Analyze ===
2.1	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.
	546
31.1	547	[[image:image-20221021111923-27.png\|\|height="253" width="783"]]
2.1	548
31.1	549	=== 2.16.3 Battery Note ===
2.1	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
31.1	553	=== 2.16.4 Replace the battery ===
2.1	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).
	556

2.1	558
	559	Users can directly access the AT command set of the NB-IoT module.

	656	Notice, CPN01 and CPN01 share the same mother board. They use the same connection and method to update.
	657
31.1	658	== 5.2 Can I calibrate CPN01 to different soil types? ==
2.1	659
	660	CPN01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at [[this link>>url:https://www.dragino.com/downloads/downloads/LoRa_End_Node/LSE01/Calibrate_to_other_Soil_20220605.pdf]].
