	787
87.4	788	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/LS interrupt interface to detect the status for the door or window.
14.1	789
	790
43.46	791	(% style="color:blue" %)Below is the installation example:

	795	* (((
87.4	796	One pin to SN50v3-LB/LS's PA8 pin

14.1	800	)))
	801
36.1	802	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	803
43.46	804	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.

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/LS will run out very soon.

	893	==== 2.3.3.10 +5V Output ====
	894
43.50	895
87.4	896	SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling.

	898	The 5V output time can be controlled by AT Command.
	899
43.9	900	(% style="color:blue" %)AT+5VT=1000
14.1	901
	902	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	903
44.4	904	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.
