	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	643	==== 2.3.3.5 Digital Interrupt ====
	644
36.1	645	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	650
43.8	651	(% style="color:blue" %)Example to use with door sensor :
14.1	652
	653	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.
	654
	655	[[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"]]
	656
36.1	657	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	658
43.8	659	(% style="color:blue" %)~ Below is the installation example:
14.1	660
36.1	661	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	662
	663	* (((
36.1	664	One pin to SN50_v3's PA8 pin
14.1	665	)))
	666	* (((
36.1	667	The other pin to SN50_v3's VDD pin
14.1	668	)))
	669
36.1	670	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	671
	672	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.
	673
36.1	674	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	675
	676	[[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"]]
	677
	678	The above photos shows the two parts of the magnetic switch fitted to a door.
	679
	680	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.
	681
	682	The command is:
	683

	689
	690	In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
	691
	692	door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
	693

26.2	695	==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
14.1	696
26.2	697	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	698
40.1	699	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	700
40.1	701	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	702
	703	Below is the connection to SHT20/ SHT31. The connection is as below:

36.1	707
14.1	708	The device will be able to get the I2C sensor data now and upload to IoT Server.
	709

	711
	712	Convert the read byte to decimal and divide it by ten.
	713
2.1	714	Example:
	715
14.1	716	Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;
2.1	717
14.1	718	Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%

14.1	731
36.1	732	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	733
36.1	734	The working principle of this sensor is similar to the HC-SR04 ultrasonic sensor.
	735
14.1	736	The picture below shows the connection:
	737
36.1	738	[[image:image-20230512173903-6.png\|\|height="596" width="715"]]
14.1	739
36.1	740	Connect to the SN50_v3 and run AT+MOD=2 to switch to ultrasonic mode (ULT).
14.1	741
	742	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	743
	744	Example:
	745
	746	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm
	747
	748
	749
	750	==== 2.3.3.9 Battery Output - BAT pin ====
	751
	752	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.
	753
	754
	755	==== 2.3.3.10 +5V Output ====
	756
	757	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	758
	759	The 5V output time can be controlled by AT Command.
	760
43.9	761	(% style="color:blue" %)AT+5VT=1000
14.1	762
	763	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	764
	765	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.
	766
	767
	768
