44.3	157	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 SN50v3-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	728
	729	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.
	730
	731	[[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"]]
	732
44.2	733	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	734
	735
43.46	736	(% style="color:blue" %)Below is the installation example:
	737
44.2	738	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB as follows:
14.1	739
	740	* (((
44.2	741	One pin to SN50v3-LB's PA8 pin
14.1	742	)))
	743	* (((
44.2	744	The other pin to SN50v3-LB's VDD pin
14.1	745	)))
	746
36.1	747	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	748
43.46	749	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	750
36.1	751	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.

	755	The above photos shows the two parts of the magnetic switch fitted to a door.

14.1	813
44.2	814	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	815
43.44	816	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.

14.1	824
	825	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	826

43.50	834
44.4	835	The BAT pin of SN50v3-LB 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.
14.1	836
	837
	838	==== 2.3.3.10 +5V Output ====
	839
43.50	840
44.2	841	SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling.
14.1	842
	843	The 5V output time can be controlled by AT Command.
	844
43.9	845	(% style="color:blue" %)AT+5VT=1000
14.1	846
	847	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	848
44.4	849	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.
