	856
87.4	857	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	858
	859
43.46	860	(% style="color:blue" %)Below is the installation example:
	861

87.4	868	The other pin to SN50v3-LB/LS's VDD pin
14.1	869	)))
	870
36.1	871	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	872
43.46	873	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	874

14.1	921
43.47	922
26.2	923	The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
14.1	924
40.1	925	We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
14.1	926
87.4	927	(% style="color:red" %)Notice: Different I2C sensors have different I2C commands set and initiate process, if user want to use other I2C sensors, User need to re-write the source code to support those sensors. SHT20/ SHT31 code in SN50v3-LB/LS will be a good reference.
14.1	928
44.2	929
14.1	930	Below is the connection to SHT20/ SHT31. The connection is as below:

	942
14.1	943	Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;
2.1	944
14.1	945	Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%

14.1	960
87.4	961	The SN50v3-LB/LS 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	962
43.44	963	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.
36.1	964
14.1	965	The picture below shows the connection:
	966

43.50	969
87.4	970	Connect to the SN50v3-LB/LS and run (% style="color:blue" %)AT+MOD=2(%%) to switch to ultrasonic mode (ULT).
14.1	971
	972	The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	973
	974	Example:
	975
	976	Distance: Read: 0C2D(Hex) = 3117(D) Value: 3117 mm=311.7 cm

	978
	979	==== 2.3.3.9 Battery Output - BAT pin ====
	980
43.50	981
87.4	982	The BAT pin of SN50v3-LB/LS 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/LS will run out very soon.
14.1	983
	984
	985	==== 2.3.3.10 +5V Output ====
	986
43.50	987
87.4	988	SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling.
14.1	989
	990	The 5V output time can be controlled by AT Command.
	991
43.9	992	(% style="color:blue" %)AT+5VT=1000
14.1	993
	994	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	995
44.4	996	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.
