	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.

	695
36.1	696	Digital Interrupt refers to pin PA8, and there are different trigger methods. When there is a trigger, the SN50v3 will send a packet to the server.
14.1	697
	698	~ Interrupt connection method:
	699

14.1	701
	702	Example to use with door sensor :
	703
	704	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.
	705
	706	[[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"]]
	707
36.1	708	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	709
	710	~ Below is the installation example:
	711
36.1	712	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	713
	714	* (((
36.1	715	One pin to SN50_v3's PA8 pin
14.1	716	)))
	717	* (((
36.1	718	The other pin to SN50_v3's VDD pin
14.1	719	)))
	720
36.1	721	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	722
	723	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.
	724
36.1	725	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	726

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

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

	762
	763	Convert the read byte to decimal and divide it by ten.
	764
2.1	765	Example:
	766
14.1	767	Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;
2.1	768
14.1	769	Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%
2.1	770
14.1	771	If you want to use other I2C device, please refer the SHT20 part source code as reference.

	779	==== 2.3.3.8 Ultrasonic Sensor ====
	780
26.2	781	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	782
36.1	783	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	784
36.1	785	The working principle of this sensor is similar to the HC-SR04 ultrasonic sensor.
	786
14.1	787	The picture below shows the connection:
	788
36.1	789	[[image:image-20230512173903-6.png\|\|height="596" width="715"]]
14.1	790
36.1	791	Connect to the SN50_v3 and run AT+MOD=2 to switch to ultrasonic mode (ULT).
14.1	792
	793	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	794
	795	Example:
	796
	797	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm
	798
	799
	800
	801	==== 2.3.3.9 Battery Output - BAT pin ====
	802
	803	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.
	804
	805
	806	==== 2.3.3.10 +5V Output ====
	807
	808	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	809
	810	The 5V output time can be controlled by AT Command.
	811
	812	AT+5VT=1000
	813
	814	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	815
	816	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.
	817
	818
	819
	820	==== 2.3.3.11 BH1750 Illumination Sensor ====
