	773
44.2	774	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	775
	776
43.46	777	(% style="color:blue" %)Below is the installation example:
	778

14.1	780
	781	* (((
44.2	782	One pin to SN50v3-LB's PA8 pin

	784	* (((
44.2	785	The other pin to SN50v3-LB's VDD pin
14.1	786	)))
	787
36.1	788	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	789
43.46	790	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	791
36.1	792	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.

14.1	854
44.2	855	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	856
43.44	857	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.

14.1	865
	866	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	867

44.4	876	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	877
	878
	879	==== 2.3.3.10 +5V Output ====
	880
43.50	881
44.2	882	SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling.
14.1	883
	884	The 5V output time can be controlled by AT Command.
	885
43.9	886	(% style="color:blue" %)AT+5VT=1000
14.1	887
