154
155 == 2.1 How it works ==
156
157
158 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.
159
160
161 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
162
163
164 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.
165
166 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.
167
168
169 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from SN50v3-LB.
170
171 Each SN50v3-LB is shipped with a sticker with the default device EUI as below:

284 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.
285
286 For example:
287
288 (% 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.

677
678 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.
679
680
681 (% style="color:blue" %)**Below is the installation example:**
682
683 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50v3-LB as follows:
684
685 * (((
686 One pin to SN50v3-LB's PA8 pin
687 )))
688 * (((
689 The other pin to SN50v3-LB's VDD pin
690 )))
691
692 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.
693
694 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.
695
696 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.

699
700 The above photos shows the two parts of the magnetic switch fitted to a door.
701
702 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.
703
704 The command is:
705

711
712
713 In **MOD=1**, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
714
715 door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
716
717
718 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
719
720
721 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
722
723 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
724
725 (% 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.**
726
727
728 Below is the connection to SHT20/ SHT31. The connection is as below:
729
730 [[image:image-20230513103633-3.png||height="448" width="716"]]
731
732
733 The device will be able to get the I2C sensor data now and upload to IoT Server.
734
735 [[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"]]
736
737 Convert the read byte to decimal and divide it by ten.
738
739 **Example:**
740
741 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
742
743 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%
744
745 If you want to use other I2C device, please refer the SHT20 part source code as reference.

755
756
757 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]]
758
759 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.
760
761 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
762
763 The picture below shows the connection:
764
765 [[image:image-20230512173903-6.png||height="596" width="715"]]
766
767
768 Connect to the SN50v3-LB and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
769
770 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
771
772 **Example:**
773
774 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
775
776
777 ==== 2.3.3.9  Battery Output - BAT pin ====
778
779
780 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.
781
782
783 ==== 2.3.3.10  +5V Output ====
784
785
786 SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling. 
787
788 The 5V output time can be controlled by AT Command.
789
790 (% style="color:blue" %)**AT+5VT=1000**
791
792 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
793
794 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.
795
