160
161 == 2.1 How it works ==
162
163
164 The SN50v3-LB/LS is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the SN50v3-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
165
166
167 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
168
169
170 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
171
172 The LPS8v2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.
173
174
175 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from SN50v3-LB/LS.
176

776
777
778 (% style="color:blue" %)**Example to use with door sensor :**
779
780 The door sensor is shown at right. It is a two wire magnetic contact switch used for detecting the open/close status of doors or windows.
781
782 [[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LSN50%20%26%20LSN50-V2%20-%20LoRaWAN%20Sensor%20Node%20User%20Manual/WebHome/1656379210849-860.png?rev=1.1||alt="1656379210849-860.png"]]
783
784 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.
785
786
787 (% style="color:blue" %)**Below is the installation example:**
788
789 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB/LS as follows:
790
791 * (((
792 One pin to SN50v3-LB/LS's PA8 pin
793 )))
794 * (((
795 The other pin to SN50v3-LB/LS's VDD pin
796 )))
797
798 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.
799
800 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.
801
802 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.
803
804 [[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LSN50%20%26%20LSN50-V2%20-%20LoRaWAN%20Sensor%20Node%20User%20Manual/WebHome/1656379283019-229.png?rev=1.1||alt="1656379283019-229.png"]]
805
806 The above photos shows the two parts of the magnetic switch fitted to a door.
807
808 The software by default uses the falling edge on the signal line as an interrupt. We need to modify it to accept both the rising edge (0v ~-~-> VCC , door close) and the falling edge (VCC ~-~-> 0v , door open) as the interrupt.
809
810 The command is:

824 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
825
826
827 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
828
829 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
830
831 (% 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.**
832
833
834 Below is the connection to SHT20/ SHT31. The connection is as below:

836 [[image:image-20230610170152-2.png||height="501" width="846"]]

842
843 Convert the read byte to decimal and divide it by ten.
844
845 **Example:**
846
847 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
848
849 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

864
865 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.
866
867 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
868

874 Connect to the SN50v3-LB/LS and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
875
876 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
877
878 **Example:**
879
880 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm

882
883 ==== 2.3.3.9  Battery Output - BAT pin ====
884
885
886 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.
887
888
889 ==== 2.3.3.10  +5V Output ====
890
891
892 SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling. 
893
894 The 5V output time can be controlled by AT Command.
895
896 (% style="color:blue" %)**AT+5VT=1000**
897
898 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
899
900 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.
