	156
11.2	157	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.

	162
	163	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.
	164
	165	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	670	(% style="color:blue" %)Example to use with door sensor :
14.1	671
	672	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.
	673
	674	[[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"]]
	675
36.1	676	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	677
	678
43.46	679	(% style="color:blue" %)Below is the installation example:
	680
36.1	681	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	682
	683	* (((
36.1	684	One pin to SN50_v3's PA8 pin
14.1	685	)))
	686	* (((
36.1	687	The other pin to SN50_v3's VDD pin
14.1	688	)))
	689
36.1	690	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	691
43.46	692	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	693
36.1	694	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.

	697
	698	The above photos shows the two parts of the magnetic switch fitted to a door.
	699
	700	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.

14.1	717
43.47	718
26.2	719	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	720
40.1	721	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	722
40.1	723	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	724
	725	Below is the connection to SHT20/ SHT31. The connection is as below:

14.1	755
36.1	756	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	757
43.44	758	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.
36.1	759
14.1	760	The picture below shows the connection:
	761

43.50	764
43.44	765	Connect to the SN50_v3 and run (% style="color:blue" %)AT+MOD=2(%%) to switch to ultrasonic mode (ULT).
14.1	766
	767	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	768
	769	Example:
	770
	771	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm
	772
	773
	774	==== 2.3.3.9 Battery Output - BAT pin ====
	775
43.50	776
14.1	777	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.
	778
	779
	780	==== 2.3.3.10 +5V Output ====
	781
43.50	782
14.1	783	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	784
	785	The 5V output time can be controlled by AT Command.
	786
43.9	787	(% style="color:blue" %)AT+5VT=1000
14.1	788
	789	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	790
	791	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.
