296
297 == 2.1 How it works ==
298
299
300 The PS-LB/LS is configured as 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 activate the PS-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

304
305
306 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.
307

309
310
311 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.
312
313
314 (% style="color:blue" %)**Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.**

456 === 2.3.3 Battery Info ===
457
458
459 Check the battery voltage for PS-LB/LS.
460

462
463 Ex2: 0x0B49 = 2889mV
464
465
466 === 2.3.4 Probe Model ===
467
468
469 PS-LB/LS has different kind of probe, 4~~20mA represent the full scale of the measuring range. So a 12mA output means different meaning for different probe. 
470
471 For example.

478
479 The probe model field provides the convenient for server to identical how it should parse the 4~~20mA sensor value and get the correct value.
480
481
482 When connecting to current sensors sold by our company, you can convert current readings to corresponding values by simply configuring the [[AT+PROBE>>||anchor="H3.3.4SettheProbeModel"]] command. If you prefer not to configure this command on the sensor, you can uniformly handle the conversion in the payload decoder instead.
483
484 **Examples for decoder implementation:**
485
486 ~1. For AT+PROBE=0005, add the following processing in your decoder:
487
488 [[image:image-20250512144042-1.png]]
489
490 [[image:image-20250512144122-2.png]]
491
492 2. For AT+PROBE=0102, add the following processing in your decoder(Corresponding to the position shown in the above screenshot).
493
494 bytes[i]=0x01;bytes[1+i]=0x02;
495
496 bytes[2]=0x01;bytes[3]=0x02;
497
498
499 === 2.3.5 0~~20mA value (IDC_IN) ===
500
501
502 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
503
504 Example:
505
506 27AE(H) = 10158 (D)/1000 = 10.158mA.
507
508
509 Instead of pressure probe, User can also connect a general 4~~20mA in this port to support different types of 4~~20mA sensors. below is the connection example:
510
511 [[image:image-20230225154759-1.png||height="408" width="741"]]
512
513
514 === 2.3.6 0~~30V value (pin VDC_IN) ===
515
516
517 Measure the voltage value. The range is 0 to 30V.
518
519 Example:
520
521 138E(H) = 5006(D)/1000= 5.006V
522
523
524 === 2.3.7 IN1&IN2&INT pin ===
525
526
527 IN1 and IN2 are used as digital input pins.
528
529 Example:
530
531 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
532
533 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
534
535
536 This data field shows if this packet is generated by Interrupt Pin or not. [[Click here>>||anchor="H3.3.2SetInterruptMode"]] for the hardware and software set up. Note: The Internet Pin is a separate pin in the screw terminal.
537
538 Example:
539
540 09 (H): (0x09&0x02)>>1=1    The level of the interrupt pin.
541
542 09 (H): 0x09&0x01=1              0x00: Normal uplink packet.
543
544 0x01: Interrupt Uplink Packet.

588
589 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
590
591 Step 2: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:

600
601 Step 4: Create PS-LB/LS product.

625 == 2.6 Datalog Feature (Since V1.1) ==
626
627
628 When a user wants to retrieve sensor value, he can send a poll command from the IoT platform to ask the sensor to send value in the required time slot.
629
630
631 === 2.6.1 Unix TimeStamp ===
632
633
634 PS-LB uses Unix TimeStamp format based on
635
636 [[image:image-20250401163826-3.jpeg]]
637
638 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
639
640 Below is the converter example:
641
642 [[image:image-20250401163906-4.jpeg]]
643
644
645 === 2.6.2 Set Device Time ===
646
647
648 There are two ways to set the device's time:
649
650
651 ~1. Through LoRaWAN MAC Command (Default settings)
652
653 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
654
655 Once CPL01 Joined the LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL01. If CPL01 fails to get the time from the server, CPL01 will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/CPL01%20LoRaWAN%20Outdoor%20PulseContact%20%20Sensor%20Manual/#H2.3.1DeviceStatus2CFPORT3D5]]].
656
657 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
658
659
660 2. Manually Set Time
661
662 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
663
664
665 === 2.6.3 Poll sensor value ===
666
667 Users can poll sensor values based on timestamps. Below is the downlink command.
668
669 (% border="1" cellspacing="3" style="background-color:#f2f2f2; width:470px" %)
670 |=(% colspan="4" style="width: 160px; background-color:#4F81BD;color:white" %)Downlink Command to poll Open/Close status (0x31)

673 Timestamp end
674 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
675
676 Timestamp start and Timestamp end-use Unix TimeStamp format as mentioned above. Devices will reply with all data logs during this period, using the uplink interval.
677
678 For example, downlink command[[image:image-20250117104812-1.png]]
679
680 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data
681
682 Uplink Internal =5s，means PS-LB will send one packet every 5s. range 5~~255s.
683

712
713 Poll Message Flag: 1: This message is a poll message reply.
714
715 * Poll Message Flag is set to 1.
716
717 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
718
719 For example, in US915 band, the max payload for different DR is:
720
721 a) DR0: max is 11 bytes so one entry of data
722
723 b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
724
725 c) DR2: total payload includes 11 entries of data
726
727 d) DR3: total payload includes 22 entries of data.
728
729 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
730
731 Example:
732
733 If PS-LB-NA has below data inside Flash:
734

1162 Downlink Command: 0x07
1163
1164 Format: Command Code (0x07) followed by 3 bytes.
1165
1166 The first byte is which power, the second and third bytes are the time to turn on.
1167
1168 * Example 1: Downlink Payload: 070101F4  ~-~-->  AT+3V3T=500
1169 * Example 2: Downlink Payload: 0701FFFF   ~-~-->  AT+3V3T=65535
1170 * Example 3: Downlink Payload: 070203E8  ~-~-->  AT+5VT=1000
1171 * Example 4: Downlink Payload: 07020000  ~-~-->  AT+5VT=0
1172 * Example 5: Downlink Payload: 070301F4  ~-~-->  AT+12VT=500
1173 * Example 6: Downlink Payload: 07030000  ~-~-->  AT+12VT=0
1174
1175 Note: Before v1.2, the maximum settable time of 3V3T, 5VT and 12VT is 65535 milliseconds. After v1.2, the maximum settable time of 3V3T, 5VT and 12VT is 180 seconds.
1176
1177 Therefore, the corresponding downlink command is increased by one byte to five bytes.
1178

1304
1305
1306 Test the current values at the depth of different liquids and convert them to a linear scale.
1307 Replace its ratio with the ratio of water to current in the decoder.
1308
1309 Example:
1310
1311 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1312
1313 Calculate scale factor:
1314 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1315
1316 Calculation formula:
1317
1318 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1319
1320 Actual calculations:
1321
1322 Use this formula to calculate the value corresponding to the current at a depth of 1.5 meters: (6.918-5.035)/1.86470588235294+0.51=1.519810726
