	855
87.4	856	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	857
	858
43.46	859	(% style="color:blue" %)Below is the installation example:
	860
87.4	861	Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB/LS as follows:

	863	* (((
87.4	864	One pin to SN50v3-LB/LS's PA8 pin

87.4	867	The other pin to SN50v3-LB/LS's VDD pin
14.1	868	)))
	869
36.1	870	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	871
43.46	872	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	873

14.1	920
43.47	921
26.2	922	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	923
40.1	924	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	925
87.4	926	(% 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	927
44.2	928
14.1	929	Below is the connection to SHT20/ SHT31. The connection is as below:

	941
14.1	942	Temperature: Read:0116(H) = 278(D) Value: 278 /10=27.8℃;
2.1	943
14.1	944	Humidity: Read:0248(H)=584(D) Value: 584 / 10=58.4, So 58.4%

14.1	959
87.4	960	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	961
43.44	962	The working principle of this sensor is similar to the (% style="color:blue" %)HC-SR04(%%) ultrasonic sensor.
36.1	963
14.1	964	The picture below shows the connection:

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

	977
	978	==== 2.3.3.9 Battery Output - BAT pin ====
	979
43.50	980
87.4	981	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	982
	983
	984	==== 2.3.3.10 +5V Output ====
	985
43.50	986
87.4	987	SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling.
14.1	988
	989	The 5V output time can be controlled by AT Command.
	990
43.9	991	(% style="color:blue" %)AT+5VT=1000
14.1	992
	993	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	994
44.4	995	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.
