	788
87.4	789	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	790
	791
43.46	792	(% style="color:blue" %)Below is the installation example:

	796	* (((
87.4	797	One pin to SN50v3-LB/LS's PA8 pin

14.1	801	)))
	802
36.1	803	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	804
43.46	805	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.

	894	==== 2.3.3.10 +5V Output ====
	895
43.50	896
87.4	897	SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling.

	899	The 5V output time can be controlled by AT Command.
	900
43.9	901	(% style="color:blue" %)AT+5VT=1000
14.1	902
	903	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	904
44.4	905	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.
