159
160 == 2.1 How it works ==
161
162
163 The SN50v3-LB 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. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
164
165
166 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
167
168
169 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.
170
171 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.
172
173
174 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from SN50v3-LB.
175

767 ==== 2.3.3.5 Digital Interrupt ====
768
769
770 Digital Interrupt refers to pin PA8, and there are different trigger methods. When there is a trigger, the SN50v3-LB will send a packet to the server.

775
776
777 (% style="color:blue" %)**Example to use with door sensor :**
778
779 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.
780
781 [[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"]]
782
783 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.
784
785
786 (% style="color:blue" %)**Below is the installation example:**
787
788 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB as follows:
789
790 * (((
791 One pin to SN50v3-LB's PA8 pin
792 )))
793 * (((
794 The other pin to SN50v3-LB's VDD pin
795 )))
796
797 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.
798
799 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.
800
801 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.
802
803 [[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"]]
804
805 The above photos shows the two parts of the magnetic switch fitted to a door.
806
807 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.
808
809 The command is:

821
822
823 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
824
825
826 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
827
828 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
829
830 (% 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 will be a good reference.**
831
832
833 Below is the connection to SHT20/ SHT31. The connection is as below:
834
835 [[image:image-20230610170152-2.png||height="501" width="846"]]
836
837

841
842 Convert the read byte to decimal and divide it by ten.
843
844 **Example:**
845
846 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
847
848 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

863
864 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.
865
866 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
867
868 The picture below shows the connection:

872
873 Connect to the SN50v3-LB and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
874
875 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
876
877 **Example:**
878
879 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
880
881
882 ==== 2.3.3.9  Battery Output - BAT pin ====
883
884
885 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.
886
887
888 ==== 2.3.3.10  +5V Output ====
889
890
891 SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling. 
892
893 The 5V output time can be controlled by AT Command.
894
895 (% style="color:blue" %)**AT+5VT=1000**
896
897 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
898
899 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.
