	152
11.2	153	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.

14.1	703	==== 2.3.3.5 Digital Interrupt ====
	704
36.1	705	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	706
	707	~ Interrupt connection method:
	708
36.1	709	[[image:image-20230513105351-5.png\|\|height="147" width="485"]]
14.1	710
	711	Example to use with door sensor :
	712
	713	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.
	714
	715	[[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"]]
	716
36.1	717	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	718
	719	~ Below is the installation example:
	720
36.1	721	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	722
	723	* (((
36.1	724	One pin to SN50_v3's PA8 pin
14.1	725	)))
	726	* (((
36.1	727	The other pin to SN50_v3's VDD pin
14.1	728	)))
	729
36.1	730	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	731
	732	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.
	733
36.1	734	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	735
	736	[[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/1656379283019-229.png?rev=1.1\|\|alt="1656379283019-229.png"]]
	737
	738	The above photos shows the two parts of the magnetic switch fitted to a door.
	739
	740	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.
	741
	742	The command is:
	743
36.1	744	AT+INTMOD1=1 ~/~/(more info about INMOD please refer [[AT Command Manual>>url:http://www.dragino.com/downloads/index.php?dir=LSN50-LoRaST/&file=DRAGINO_LSN50_AT_Commands_v1.5.1.pdf]]. )
14.1	745
	746	Below shows some screen captures in TTN V3:

	749
	750	In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
	751
	752	door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
	753
	754
26.2	755	==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
14.1	756
26.2	757	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	758
40.1	759	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	760
40.1	761	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	762
	763	Below is the connection to SHT20/ SHT31. The connection is as below:
	764
	765
40.1	766	[[image:image-20230513103633-3.png\|\|height="448" width="716"]]
36.1	767
14.1	768	The device will be able to get the I2C sensor data now and upload to IoT Server.
	769
	770	[[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/1656379664142-345.png?rev=1.1\|\|alt="1656379664142-345.png"]]
	771
	772	Convert the read byte to decimal and divide it by ten.
	773
2.1	774	Example:
	775
14.1	776	Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;
2.1	777
14.1	778	Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%
2.1	779
14.1	780	If you want to use other I2C device, please refer the SHT20 part source code as reference.

	788	==== 2.3.3.8 Ultrasonic Sensor ====
	789
26.2	790	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	791
36.1	792	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	793
36.1	794	The working principle of this sensor is similar to the HC-SR04 ultrasonic sensor.
	795
14.1	796	The picture below shows the connection:
	797
36.1	798	[[image:image-20230512173903-6.png\|\|height="596" width="715"]]
14.1	799
36.1	800	Connect to the SN50_v3 and run AT+MOD=2 to switch to ultrasonic mode (ULT).
14.1	801
	802	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	803
	804	Example:
	805
	806	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm
	807
	808
	809
	810	==== 2.3.3.9 Battery Output - BAT pin ====
	811
	812	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.
	813
	814
	815	==== 2.3.3.10 +5V Output ====
	816
	817	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	818
	819	The 5V output time can be controlled by AT Command.
	820
	821	AT+5VT=1000
	822
	823	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	824
	825	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.
	826
	827
	828
