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 SN50v3-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

	750
	751	[[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"]]
	752
44.2	753	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 SN50v3-LB interrupt interface to detect the status for the door or window.
14.1	754
	755
43.46	756	(% style="color:blue" %)Below is the installation example:
	757

	760	* (((

	763	* (((
44.2	764	The other pin to SN50v3-LB's VDD pin
14.1	765	)))
	766
36.1	767	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	768
43.46	769	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	770
36.1	771	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.

44.2	834	The SN50v3-LB 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	835
43.44	836	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic 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.

	857
	858	==== 2.3.3.10 +5V Output ====
	859
43.50	860
44.2	861	SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling.
14.1	862
	863	The 5V output time can be controlled by AT Command.
	864
43.9	865	(% style="color:blue" %)AT+5VT=1000
14.1	866
	867	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	868
44.4	869	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.
