159
160 == 2.1 How it works ==
161
162
163 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.
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/LS.
175

772 ==== 2.3.3.5 Digital Interrupt ====
773
774
775 Digital Interrupt refers to pin PA8, and there are different trigger methods. When there is a trigger, the SN50v3-LB/LS will send a packet to the server.

780
781
782 (% style="color:blue" %)**Example to use with door sensor :**
783
784 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.
785
786 [[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"]]
787
788 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.
789
790
791 (% style="color:blue" %)**Below is the installation example:**
792
793 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB/LS as follows:
794
795 * (((
796 One pin to SN50v3-LB/LS's PA8 pin
797 )))
798 * (((
799 The other pin to SN50v3-LB/LS's VDD pin
800 )))
801
802 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.
803
804 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.
805
806 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.
807
808 [[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"]]
809
810 The above photos shows the two parts of the magnetic switch fitted to a door.
811
812 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.
813
814 The command is:

823 In **MOD=1**, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:

827
828 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
829
830
831 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
832
833 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
834
835 (% 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.**
836
837
838 Below is the connection to SHT20/ SHT31. The connection is as below:

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

846
847 Convert the read byte to decimal and divide it by ten.
848
849 **Example:**
850
851 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
852
853 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

868
869 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.
870
871 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
872

878 Connect to the SN50v3-LB/LS and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
879
880 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
881
882 **Example:**
883
884 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm

886
887 ==== 2.3.3.9  Battery Output - BAT pin ====
888
889
890 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.
891
892
893 ==== 2.3.3.10  +5V Output ====
894
895
896 SN50v3-LB/LS will enable +5V output before all sampling and disable the +5v after all sampling. 
897
898 The 5V output time can be controlled by AT Command.
899
900 (% style="color:blue" %)**AT+5VT=1000**
901
902 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
903
904 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.

934 Since the device can only detect a pulse period of 50ms when [[AT+PWMSET=0>>||anchor="H3.3.8PWMsetting"]] (counting in microseconds), it is necessary to change the value of PWMSET according to the frequency of input capture.
