606 ==== 2.3.3.5 Digital Interrupt ====
607
608 Digital Interrupt refers to pin PB14, and there are different trigger methods. When there is a trigger, the SN50v3 will send a packet to the server.
609
610 **~ Interrupt connection method:**
611
612 [[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/1656379178634-321.png?rev=1.1||alt="1656379178634-321.png"]]
613
614 **Example to use with door sensor :**
615
616 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.
617
618 [[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"]]
619
620 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 LSN50 interrupt interface to detect the status for the door or window.
621
622 **~ Below is the installation example:**
623
624 Fix one piece of the magnetic sensor to the door and connect the two pins to LSN50 as follows:
625
626 * (((
627 One pin to LSN50's PB14 pin
628 )))
629 * (((
630 The other pin to LSN50's VCC pin
631 )))
632
633 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 PB14 will be at the VCC voltage.
634
635 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.
636
637 When door sensor is shorted, there will extra power consumption in the circuit, the extra current is 3v3/R14 = 3v2/1Mohm = 0.3uA which can be ignored.

641 The above photos shows the two parts of the magnetic switch fitted to a door.
642
643 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.
644
645 The command is:
646
647 **AT+INTMOD=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]]**. **)

653 In MOD=1, user can use byte 6 to see the status for door open or close. TTN V3 decoder is as below:
654
655 door= (bytes[6] & 0x80)? "CLOSE":"OPEN";
656
657 **Notice for hardware version LSN50 v1 < v1.3** (produced before 2018-Nov).
658
659 In this hardware version, there is no R14 resistance solder. When use the latest firmware, it should set AT+INTMOD=0 to close the interrupt. If user need to use Interrupt in this hardware version, user need to solder R14 with 10M resistor and C1 (0.1uF) on board.

664 ==== 2.3.3.6 I2C Interface (SHT20) ====
665
666 The PB6(SDA) and PB7(SCK) are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
667
668 We have made an example to show how to use the I2C interface to connect to the SHT20 Temperature and Humidity Sensor. This is supported in the stock firmware since v1.5 with **AT+MOD=1 (default value).**
669
670 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 code in LSN50 will be a good reference.
671
672 Below is the connection to SHT20/ SHT31. The connection is as below:

680 Convert the read byte to decimal and divide it by ten.
681
682 **Example:**
683
684 Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
685
686 Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

695
696 ==== 2.3.3.8 Ultrasonic Sensor ====
697
698 The LSN50 v1.5 firmware supports ultrasonic sensor (with AT+MOD=2) such as SEN0208 from DF-Robot. 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]]
699
700 The LSN50 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.
701
702 The picture below shows the connection:

704 [[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/1656380061365-178.png?rev=1.1||alt="1656380061365-178.png"]]
705
706 Connect to the LSN50 and run **AT+MOD=2** to switch to ultrasonic mode (ULT).
707
708 The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
709

728 ==== 2.3.3.9  Battery Output - BAT pin ====
729
730 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.
731
732
733 ==== 2.3.3.10  +5V Output ====
734
735 SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling. 
736
737 The 5V output time can be controlled by AT Command.
738
739 **AT+5VT=1000**
740
741 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
742
743 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.
744

780
781
782 == 2.5 Datalog Feature ==
783
784
785 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, S31x-LB will store the reading for future retrieving purposes.
786
787
788 === 2.5.1 Ways to get datalog via LoRaWAN ===
789
790
791 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], S31x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-LB will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.
792
793 * a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
794 * b) S31x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but S31x-LB won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if S31x-LB gets a ACK, S31x-LB will consider there is a network connection and resend all NONE-ACK messages.
795
796 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
797
798 [[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LHT65N%20LoRaWAN%20Temperature%20%26%20Humidity%20Sensor%20Manual/WebHome/image-20220703111700-2.png?width=1119&height=381&rev=1.1||alt="图片-20220703111700-2.png" height="381" width="1119"]]
799
800 === 2.5.2 Unix TimeStamp ===
801
802
803 S31x-LB uses Unix TimeStamp format based on
804
805 [[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LHT65N%20LoRaWAN%20Temperature%20%26%20Humidity%20Sensor%20Manual/WebHome/image-20220523001219-11.png?width=627&height=97&rev=1.1||alt="图片-20220523001219-11.png" height="97" width="627"]]
806
807 User can get this time from link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :

812
813 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
814
815
816 === 2.5.3 Set Device Time ===
817
818
819 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
820
821 Once S31x-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to S31x-LB. If S31x-LB fails to get the time from the server, S31x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
822
823 (% style="color:red" %)**Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
824
825
826 === 2.5.4 Datalog Uplink payload (FPORT~=3) ===
827

844
845 **No ACK Message**:  1: This message means this payload is fromn Uplink Message which doesn't get ACK from the server before ( for **PNACKMD=1** feature)
846
847 **Poll Message Flag**: 1: This message is a poll message reply.
848
849 * Poll Message Flag is set to 1.
850
851 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
852
853 For example, in US915 band, the max payload for different DR is:
854
855 **a) DR0:** max is 11 bytes so one entry of data
856
857 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
858
859 **c) DR2:** total payload includes 11 entries of data
860
861 **d) DR3: **total payload includes 22 entries of data.
862
863 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
864

866 **Example:**
867
868 If S31x-LB has below data inside Flash:
869
870 [[image:1682646494051-944.png]]
