	159
11.2	160	The SN50v3-LB is configured as (% style="color:#037691" %)LoRaWAN OTAA Class A(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the S31x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
2.1	161
	162
	163	== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==

	165
	166	Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
	167
	168	The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

43.8	675	(% style="color:blue" %)Example to use with door sensor :
14.1	676
	677	The door sensor is shown at right. It is a two wire magnetic contact switch used for detecting the open/close status of doors or windows.
	678
	679	[[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LSN50%20%26%20LSN50-V2%20-%20LoRaWAN%20Sensor%20Node%20User%20Manual/WebHome/1656379210849-860.png?rev=1.1\|\|alt="1656379210849-860.png"]]
	680
36.1	681	When the two pieces are close to each other, the 2 wire output will be short or open (depending on the type), while if the two pieces are away from each other, the 2 wire output will be the opposite status. So we can use SN50_v3 interrupt interface to detect the status for the door or window.
14.1	682
	683
43.46	684	(% style="color:blue" %)Below is the installation example:
	685
36.1	686	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	687
	688	* (((
36.1	689	One pin to SN50_v3's PA8 pin
14.1	690	)))
	691	* (((
36.1	692	The other pin to SN50_v3's VDD pin
14.1	693	)))
	694
36.1	695	Install the other piece to the door. Find a place where the two pieces will be close to each other when the door is closed. For this particular magnetic sensor, when the door is closed, the output will be short, and PA8 will be at the VCC voltage.
14.1	696
43.46	697	Door sensors have two types: (% style="color:blue" %) NC (Normal close)(%%) and (% style="color:blue" %)NO (normal open)(%%). The connection for both type sensors are the same. But the decoding for payload are reverse, user need to modify this in the IoT Server decoder.
14.1	698
36.1	699	When door sensor is shorted, there will extra power consumption in the circuit, the extra current is 3v3/R14 = 3v3/1Mohm = 3uA which can be ignored.

	702
	703	The above photos shows the two parts of the magnetic switch fitted to a door.
	704
	705	The software by default uses the falling edge on the signal line as an interrupt. We need to modify it to accept both the rising edge (0v ~-~-> VCC , door close) and the falling edge (VCC ~-~-> 0v , door open) as the interrupt.
	706

14.1	722
43.47	723
26.2	724	The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
14.1	725
40.1	726	We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
14.1	727
40.1	728	Notice: Different I2C sensors have different I2C commands set and initiate process, if user want to use other I2C sensors, User need to re-write the source code to support those sensors. SHT20/ SHT31 code in SN50_v3 will be a good reference.
14.1	729
	730	Below is the connection to SHT20/ SHT31. The connection is as below:

14.1	760
36.1	761	The SN50_v3 detects the pulse width of the sensor and converts it to mm output. The accuracy will be within 1 centimeter. The usable range (the distance between the ultrasonic probe and the measured object) is between 24cm and 600cm.
14.1	762
43.44	763	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.
36.1	764
14.1	765	The picture below shows the connection:
	766

43.50	769
43.44	770	Connect to the SN50_v3 and run (% style="color:blue" %)AT+MOD=2(%%) to switch to ultrasonic mode (ULT).
14.1	771
	772	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	773
	774	Example:
	775
	776	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm
	777
	778
	779	==== 2.3.3.9 Battery Output - BAT pin ====
	780
43.50	781
14.1	782	The BAT pin of SN50v3 is connected to the Battery directly. If users want to use BAT pin to power an external sensor. User need to make sure the external sensor is of low power consumption. Because the BAT pin is always open. If the external sensor is of high power consumption. the battery of SN50v3-LB will run out very soon.
	783
	784
	785	==== 2.3.3.10 +5V Output ====
	786
43.50	787
14.1	788	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	789
	790	The 5V output time can be controlled by AT Command.
	791
43.9	792	(% style="color:blue" %)AT+5VT=1000
14.1	793
	794	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	795
	796	By default the AT+5VT=500. If the external sensor which require 5v and require more time to get stable state, user can use this command to increase the power ON duration for this sensor.
