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 S31x-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
167 Each SN50v3-LB is shipped with a sticker with the default device EUI as below:

277 === 2.3.2 Working Modes & Sensor Data. Uplink via FPORT~=2 ===
278
279
280 SN50v3 has different working mode for the connections of different type of sensors. This section describes these modes. Use can use the AT Command AT+MOD to set SN50v3 to different working modes.
281
282 For example:
283
284 **AT+MOD=2  ** ~/~/ will set the SN50v3 to work in MOD=2 distance mode which target to measure distance via Ultrasonic Sensor.
285
286
287 (% style="color:red" %) **Important Notice:**
288
289 1. Some working modes has payload more than 12 bytes, The US915/AU915/AS923 frequency bands' definition has maximum 11 bytes in **DR0**. Server sides will see NULL payload while SN50v3 transmit in DR0 with 12 bytes payload.
290 1. All modes share the same Payload Explanation from HERE.
291 1. By default, the device will send an uplink message every 20 minutes.
292
293 ==== 2.3.2.1  MOD~=1 (Default Mode) ====

427 1. Zero calibration. Don't put anything on load cell and run **AT+WEIGRE** to calibrate to Zero gram.
428 1. Adjust calibration factor (default value 400): Put a known weight thing on load cell and run **AT+WEIGAP** to adjust the Calibration Factor.

639 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.
640
641 [[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"]]
642
643 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 SN50_v3 interrupt interface to detect the status for the door or window.
644
645 (% style="color:blue" %)** Below is the installation example:**
646
647 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
648
649 * (((
650 One pin to SN50_v3's PA8 pin
651 )))
652 * (((
653 The other pin to SN50_v3's VDD pin
654 )))
655
656 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.
657
658 Door sensors have two types: ** NC (Normal close)** and **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.
659
660 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.

663
664 The above photos shows the two parts of the magnetic switch fitted to a door.
665
666 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.
667
668 The command is:
669
670 (% style="color:blue" %)**AT+INTMOD1=1   ** (%%) ~/~/(more info about INMOD please refer** **[[**AT Command Manual**>>url:http://www.dragino.com/downloads/index.php?dir=LSN50-LoRaST/&file=DRAGINO_LSN50_AT_Commands_v1.5.1.pdf]]**. **)

675
676 In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
677
678 door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
679
680
681 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
682
683 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
684
685 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
686
687 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 SN50_v3 will be a good reference.
688
689 Below is the connection to SHT20/ SHT31. The connection is as below:
690
691
692 [[image:image-20230513103633-3.png||height="448" width="716"]]
693
694 The device will be able to get the I2C sensor data now and upload to IoT Server.
695
696 [[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"]]
697
698 Convert the read byte to decimal and divide it by ten.
699
700 **Example:**
701
702 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
703
704 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%
705
706 If you want to use other I2C device, please refer the SHT20 part source code as reference.

713
714 ==== 2.3.3.8 Ultrasonic Sensor ====
715
716 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]]
717
718 The SN50_v3 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.
719
720 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
721
722 The picture below shows the connection:
723
724 [[image:image-20230512173903-6.png||height="596" width="715"]]
725
726 Connect to the SN50_v3 and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
727
728 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
729
730 **Example:**
731
732 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
733
734
735
736 ==== 2.3.3.9  Battery Output - BAT pin ====
737
738 The BAT pin of SN50v3 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.
739
740
741 ==== 2.3.3.10  +5V Output ====
742
743 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
744
745 The 5V output time can be controlled by AT Command.
746
747 (% style="color:blue" %)**AT+5VT=1000**
748
749 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
750
751 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.
752
753
754
