149
150 == 2.1 How it works ==
151
152
153 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.
154
155
156 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
157
158
159 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.
160
161 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.
162
163
164 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from SN50v3-LB.
165
166 Each SN50v3-LB is shipped with a sticker with the default device EUI as below:

277
278
279 SN50v3-LB has different working mode for the connections of different type of sensors. This section describes these modes. Use can use the AT Command (% style="color:blue" %)**AT+MOD**(%%) to set SN50v3-LB to different working modes.
280
281 For example:
282
283 (% style="color:blue" %)**AT+MOD=2  ** (%%) ~/~/ will set the SN50v3 to work in MOD=2 distance mode which target to measure distance via Ultrasonic Sensor.
284
285
286 (% style="color:red" %) **Important Notice:**
287
288 ~1. Some working modes has payload more than 12 bytes, The US915/AU915/AS923 frequency bands' definition has maximum 11 bytes in (% style="color:blue" %)**DR0**(%%). Server sides will see NULL payload while SN50v3-LB transmit in DR0 with 12 bytes payload.
289
290 2. All modes share the same Payload Explanation from HERE.

757 ==== 2.3.3.5 Digital Interrupt ====
758
759
760 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.

765
766
767 (% style="color:blue" %)**Example to use with door sensor :**
768
769 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.
770
771 [[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"]]
772
773 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.
774
775
776 (% style="color:blue" %)**Below is the installation example:**
777
778 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB as follows:
779
780 * (((
781 One pin to SN50v3-LB's PA8 pin
782 )))
783 * (((
784 The other pin to SN50v3-LB's VDD pin
785 )))
786
787 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.
788
789 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.
790
791 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.
792
793 [[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"]]
794
795 The above photos shows the two parts of the magnetic switch fitted to a door.
796
797 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.
798
799 The command is:

811
812
813 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
814
815
816 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
817
818 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
819
820 (% 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.**
821
822
823 Below is the connection to SHT20/ SHT31. The connection is as below:
824
825 [[image:image-20230610170152-2.png||height="501" width="846"]]
826
827
828 The device will be able to get the I2C sensor data now and upload to IoT Server.

831
832 Convert the read byte to decimal and divide it by ten.
833
834 **Example:**
835
836 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
837
838 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

853
854 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.
855
856 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
857
858 The picture below shows the connection:

862
863 Connect to the SN50v3-LB and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
864
865 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
866
867 **Example:**
868
869 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
870
871
872 ==== 2.3.3.9  Battery Output - BAT pin ====
873
874
875 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.
876
877
878 ==== 2.3.3.10  +5V Output ====
879
880
881 SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling. 
882
883 The 5V output time can be controlled by AT Command.
884
885 (% style="color:blue" %)**AT+5VT=1000**
886
887 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
888
889 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.
