	150
	151
11.2	152	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	153
	154
	155	== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
	156
	157
	158	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.
	159
	160	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.

14.1	700
	701	Example to use with door sensor :
	702
	703	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.
	704
	705	[[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"]]
	706
36.1	707	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	708
	709	~ Below is the installation example:
	710
36.1	711	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	712
	713	* (((
36.1	714	One pin to SN50_v3's PA8 pin
14.1	715	)))
	716	* (((
36.1	717	The other pin to SN50_v3's VDD pin
14.1	718	)))
	719
36.1	720	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	721
	722	Door sensors have two types: NC (Normal close) and 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.
	723
36.1	724	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.
14.1	725

	727
	728	The above photos shows the two parts of the magnetic switch fitted to a door.
	729
	730	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.
	731
	732	The command is:

26.2	745	==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
14.1	746
26.2	747	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	748
26.2	749	We have made an example to show how to use the I2C interface to connect to the SHT20 Temperature and Humidity Sensor.
14.1	750
26.2	751	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 code in SN50_v3 will be a good reference.
14.1	752
	753	Below is the connection to SHT20/ SHT31. The connection is as below:
	754
	755
36.1	756	[[image:image-20230513103633-3.png\|\|height="636" width="1017"]]
	757
14.1	758	The device will be able to get the I2C sensor data now and upload to IoT Server.
	759

	761
	762	Convert the read byte to decimal and divide it by ten.
	763
2.1	764	Example:
	765
14.1	766	Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;
2.1	767
14.1	768	Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%
2.1	769
14.1	770	If you want to use other I2C device, please refer the SHT20 part source code as reference.

	778	==== 2.3.3.8 Ultrasonic Sensor ====
	779
26.2	780	This Fundamental Principles of this sensor can be found at this link: [[https:~~/~~/wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU~~_~~__SEN0208>>url:https://wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU___SEN0208]]
14.1	781
36.1	782	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	783
36.1	784	The working principle of this sensor is similar to the HC-SR04 ultrasonic sensor.
	785
14.1	786	The picture below shows the connection:
	787
36.1	788	[[image:image-20230512173903-6.png\|\|height="596" width="715"]]
14.1	789
36.1	790	Connect to the SN50_v3 and run AT+MOD=2 to switch to ultrasonic mode (ULT).
14.1	791
	792	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	793
	794	Example:
	795
	796	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm
	797
	798
	799
	800	==== 2.3.3.9 Battery Output - BAT pin ====
	801
	802	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.
	803
	804
	805	==== 2.3.3.10 +5V Output ====
	806
	807	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	808
	809	The 5V output time can be controlled by AT Command.
	810
	811	AT+5VT=1000
	812
	813	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	814
	815	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.
	816
	817
	818
	819	==== 2.3.3.11 BH1750 Illumination Sensor ====
