34.1	8	== 1.1 What is CPN01 NB-IoT Pulse/Contact Sensor ==
1.5	9
35.1	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
34.1	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
35.1	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.

	114
31.1	115	= 2. Use CPN01 to communicate with IoT Server =
2.1	116
31.1	117	== 2.1 How it works ==
2.1	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
31.1	123	[[image:image-20221021110615-5.png]]
2.1	124
31.1	125	== 2.2 Configure the CPN01 ==
2.1	126
31.1	127	=== 2.2.1 Test Requirement ===
2.1	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
	136
	137
	138
31.1	139	=== 2.2.2 Insert SIM card ===
2.1	140
	141	Insert the NB-IoT Card get from your provider.
	142
	143	User need to take out the NB-IoT module and insert the SIM card like below:
	144
31.1	145	[[image:image-20221021110745-6.png]]
2.1	146
31.1	147	=== 2.2.3 Connect USB – TTL to CPN01 to configure it ===
2.1	148
	149	User need to configure CPN01 via serial port to set the Server Address / Uplink Topic to define where and how-to uplink packets. CPN01 support AT Commands, user can use a USB to TTL adapter to connect to CPN01 and use AT Commands to configure it, as below.
	150
	151	Connection:
	152
	153	USB TTL GND <~-~-~-~-> GND
	154
	155	USB TTL TXD <~-~-~-~-> UART_RXD
	156
	157	USB TTL RXD <~-~-~-~-> UART_TXD
	158
	159	In the PC, use below serial tool settings:
	160
	161	* Baud: 9600
	162	* Data bits: 8
	163	* Stop bits: 1
	164	* Parity: None
	165	* Flow Control: None
	166
	167	Make sure the switch is in FLASH position, then power on device by connecting the jumper on CPN01. CPN01 will output system info once power on as below, we can enter the password: 12345678 to access AT Command input.

	342
	343	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.

	408	The CPN01 has an internal LED which is to show the status of different state.
	409
	410	* 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)
	411	* Then the LED will be on for 1 second means device is boot normally.

31.1	509	== 2.16 Battery Analysis ==
2.1	510
31.1	511	=== 2.16.1 Battery Type ===
2.1	512
	513	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.
	514
	515	The battery is designed to last for several years depends on the actually use environment and update interval.
	516
	517	The battery related documents as below:
	518

2.1	524
31.1	525	=== 2.16.2 Power consumption Analyze ===
2.1	526
	527	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.
	528
	529	Instruction to use as below:
	530
	531	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/]]
	532
	533	Step 2: Open it and choose
	534
	535	* Product Model
	536	* Uplink Interval
	537	* Working Mode
	538
	539	And the Life expectation in difference case will be shown on the right.
	540
31.1	541	[[image:image-20221021111923-27.png\|\|height="253" width="783"]]
2.1	542
31.1	543	=== 2.16.3 Battery Note ===
2.1	544
	545	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.
	546
31.1	547	=== 2.16.4 Replace the battery ===
2.1	548
	549	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).
	550

2.1	552

	650	Notice, CPN01 and CPN01 share the same mother board. They use the same connection and method to update.
	651
31.1	652	== 5.2 Can I calibrate CPN01 to different soil types? ==
2.1	653
	654	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]].
