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

670 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.
671
672 [[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"]]
673
674 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.
675
676
677 (% style="color:blue" %)**Below is the installation example:**
678
679 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB as follows:
680
681 * (((
682 One pin to SN50v3-LB's PA8 pin
683 )))
684 * (((
685 The other pin to SN50v3-LB's VDD pin
686 )))
687
688 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.
689
690 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.
691
692 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.

695
696 The above photos shows the two parts of the magnetic switch fitted to a door.
697
698 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.
699
700 The command is:
701

707
708
709 In **MOD=1**, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
710
711 door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
712
713
714 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
715
716
717 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
718
719 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
720
721 (% 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.**
722
723
724 Below is the connection to SHT20/ SHT31. The connection is as below:
725
726 [[image:image-20230513103633-3.png||height="448" width="716"]]
727
728
729 The device will be able to get the I2C sensor data now and upload to IoT Server.
730
731 [[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/1656379664142-345.png?rev=1.1||alt="1656379664142-345.png"]]
732
733 Convert the read byte to decimal and divide it by ten.
734
735 **Example:**
736
737 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
738
739 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%
740
741 If you want to use other I2C device, please refer the SHT20 part source code as reference.

749
750 ==== 2.3.3.8 Ultrasonic Sensor ====
751
752
753 This Fundamental Principles of this sensor can be found at this link: [[https:~~/~~/wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU~~_~~__SEN0208>>url:https://wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU___SEN0208]]
754
755 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.
756
757 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
758
759 The picture below shows the connection:
760
761 [[image:image-20230512173903-6.png||height="596" width="715"]]
762
763
764 Connect to the SN50v3-LB and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
765
766 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
767
768 **Example:**
769
770 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
771
772
773 ==== 2.3.3.9  Battery Output - BAT pin ====
774
775
776 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.
777
778
779 ==== 2.3.3.10  +5V Output ====
780
781
782 SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling. 
783
784 The 5V output time can be controlled by AT Command.
785
786 (% style="color:blue" %)**AT+5VT=1000**
787
788 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
789
790 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.
791
