153
154 == 2.1 How it works ==
155
156
157 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.
158

160 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
161
162
163 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.
164
165 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.
166
167
168 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from SN50v3-LB.
169

280 === 2.3.2 Working Modes & Sensor Data. Uplink via FPORT~=2 ===
281
282
283 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.
284
285 For example:
286
287 **AT+MOD=2  ** ~/~/ will set the SN50v3 to work in MOD=2 distance mode which target to measure distance via Ultrasonic Sensor.
288
289
290 (% style="color:red" %) **Important Notice:**
291
292 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.
293 1. All modes share the same Payload Explanation from HERE.
294 1. By default, the device will send an uplink message every 20 minutes.

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

669 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.
670
671 [[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"]]
672
673 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.
674
675
676 (% style="color:blue" %)**Below is the installation example:**
677
678 Fix one piece of the magnetic sensor to the door and connect the two pins to SN50_v3 as follows:
679
680 * (((
681 One pin to SN50_v3's PA8 pin
682 )))
683 * (((
684 The other pin to SN50_v3's VDD pin
685 )))
686
687 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.
688
689 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.
690
691 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.

694
695 The above photos shows the two parts of the magnetic switch fitted to a door.
696
697 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.
698
699 The command is:

706
707 In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
708
709 door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
710
711
712 ==== 2.3.3.6 I2C Interface (SHT20 & SHT31) ====
713
714 The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
715
716 We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.
717
718 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.
719
720 Below is the connection to SHT20/ SHT31. The connection is as below:
721
722
723 [[image:image-20230513103633-3.png||height="448" width="716"]]
724
725 The device will be able to get the I2C sensor data now and upload to IoT Server.
726
727 [[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"]]
728
729 Convert the read byte to decimal and divide it by ten.
730
731 **Example:**
732
733 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
734
735 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%
736
737 If you want to use other I2C device, please refer the SHT20 part source code as reference.

742 Refer [[Ultrasonic Sensor section>>||anchor="H2.3.3.8UltrasonicSensor"]].
743
744
745 ==== 2.3.3.8 Ultrasonic Sensor ====
746
747 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]]
748
749 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.
750
751 The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
752
753 The picture below shows the connection:
754
755 [[image:image-20230512173903-6.png||height="596" width="715"]]
756
757 Connect to the SN50_v3 and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
758
759 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
760
761 **Example:**
762
763 Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
764
765
766
767 ==== 2.3.3.9  Battery Output - BAT pin ====
768
769 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.
770
771
772 ==== 2.3.3.10  +5V Output ====
773
774 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
775
776 The 5V output time can be controlled by AT Command.
777
778 (% style="color:blue" %)**AT+5VT=1000**
779
780 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
781
782 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.
783
784
785
