	152
	153
11.2	154	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	155
	156

43.8	663	(% style="color:blue" %)Example to use with door sensor :
14.1	664
	665	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.
	666
	667	[[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"]]
	668
36.1	669	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	670
	671
43.46	672	(% style="color:blue" %)Below is the installation example:
	673
36.1	674	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
14.1	675
	676	* (((
36.1	677	One pin to SN50_v3's PA8 pin
14.1	678	)))
	679	* (((
36.1	680	The other pin to SN50_v3's VDD pin
14.1	681	)))
	682
36.1	683	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	684
43.46	685	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	686
36.1	687	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.

	691	The above photos shows the two parts of the magnetic switch fitted to a door.
	692
	693	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	710
43.47	711
26.2	712	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	713
40.1	714	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	715
40.1	716	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	717
	718	Below is the connection to SHT20/ SHT31. The connection is as below:

14.1	748
36.1	749	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	750
43.44	751	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.
36.1	752
14.1	753	The picture below shows the connection:
	754

43.50	757
43.44	758	Connect to the SN50_v3 and run (% style="color:blue" %)AT+MOD=2(%%) to switch to ultrasonic mode (ULT).
14.1	759
	760	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	761
	762	Example:
	763
	764	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm

	766
	767	==== 2.3.3.9 Battery Output - BAT pin ====
	768
43.50	769
14.1	770	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.
	771
	772
	773	==== 2.3.3.10 +5V Output ====
	774
43.50	775
14.1	776	SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.
	777
	778	The 5V output time can be controlled by AT Command.
	779
43.9	780	(% style="color:blue" %)AT+5VT=1000
14.1	781
	782	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	783
	784	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.
