295
296 == 2.1 How it works ==
297
298
299 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.

303
304
305 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.

456
457
458 Check the battery voltage for PS-LB/LS.

461
462 Ex2: 0x0B49 = 2889mV
463
464
465 === 2.3.4 Probe Model ===
466
467
468 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. 
469
470 For example.

477
478 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.
479
480
481 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.
482
483 **Examples for decoder implementation:**
484
485 ~1. For AT+PROBE=0005, add the following processing in your decoder:
486
487 [[image:image-20250512144042-1.png]]
488
489 [[image:image-20250512144122-2.png]]
490
491 2. For AT+PROBE=0102, add the following processing in your decoder(Corresponding to the position shown in the above screenshot).
492
493 bytes[i]=0x01;bytes[1+i]=0x02;
494
495 bytes[2]=0x01;bytes[3]=0x02;
496
497
498 === 2.3.5 0~~20mA value (IDC_IN) ===
499
500
501 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
502
503 Example:
504
505 27AE(H) = 10158 (D)/1000 = 10.158mA.
506
507
508 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:
509
510 [[image:image-20230225154759-1.png||height="408" width="741"]]
511
512
513 === 2.3.6 0~~30V value (pin VDC_IN) ===
514
515
516 Measure the voltage value. The range is 0 to 30V.
517
518 Example:
519
520 138E(H) = 5006(D)/1000= 5.006V
521
522
523 === 2.3.7 IN1&IN2&INT pin ===
524
525
526 IN1 and IN2 are used as digital input pins.
527
528 Example:
529
530 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
531
532 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
533
534
535 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.
536
537 Example:
538
539 09 (H): (0x09&0x02)>>1=1    The level of the interrupt pin.
540
541 09 (H): 0x09&0x01=1              0x00: Normal uplink packet.
542

587
588 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
589
590 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:

624 == 2.6 Datalog Feature (Since V1.1) ==
625
626
627 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.
628
629
630 === 2.6.1 Unix TimeStamp ===
631
632
633 PS-LB uses Unix TimeStamp format based on
634
635 [[image:image-20250401163826-3.jpeg]]
636
637 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
638
639 Below is the converter example:
640
641 [[image:image-20250401163906-4.jpeg]]
642
643
644 === 2.6.2 Set Device Time ===
645
646
647 There are two ways to set the device's time:
648
649
650 ~1. Through LoRaWAN MAC Command (Default settings)
651
652 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
653
654 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]]].
655
656 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
657
658
659 2. Manually Set Time
660
661 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
662
663
664 === 2.6.3 Poll sensor value ===
665
666 Users can poll sensor values based on timestamps. Below is the downlink command.
667
668 (% border="1" cellspacing="3" style="background-color:#f2f2f2; width:470px" %)
669 |=(% colspan="4" style="width: 160px; background-color:#4F81BD;color:white" %)Downlink Command to poll Open/Close status (0x31)

672 Timestamp end
673 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
674
675 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.
676
677 For example, downlink command[[image:image-20250117104812-1.png]]
678
679 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data
680
681 Uplink Internal =5s，means PS-LB will send one packet every 5s. range 5~~255s.
682

711
712 Poll Message Flag: 1: This message is a poll message reply.
713
714 * Poll Message Flag is set to 1.
715
716 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
717
718 For example, in US915 band, the max payload for different DR is:
719
720 a) DR0: max is 11 bytes so one entry of data
721
722 b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
723
724 c) DR2: total payload includes 11 entries of data
725
726 d) DR3: total payload includes 22 entries of data.
727
728 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
729
730 Example:
731
732 If PS-LB-NA has below data inside Flash:

1161 Downlink Command: 0x07
1162
1163 Format: Command Code (0x07) followed by 3 bytes.
1164
1165 The first byte is which power, the second and third bytes are the time to turn on.
1166
1167 * Example 1: Downlink Payload: 070101F4  ~-~-->  AT+3V3T=500
1168 * Example 2: Downlink Payload: 0701FFFF   ~-~-->  AT+3V3T=65535
1169 * Example 3: Downlink Payload: 070203E8  ~-~-->  AT+5VT=1000
1170 * Example 4: Downlink Payload: 07020000  ~-~-->  AT+5VT=0
1171 * Example 5: Downlink Payload: 070301F4  ~-~-->  AT+12VT=500
1172 * Example 6: Downlink Payload: 07030000  ~-~-->  AT+12VT=0
1173
1174 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.
1175
1176 Therefore, the corresponding downlink command is increased by one byte to five bytes.
1177
1178 Example:
1179
1180 * 120s=120000ms(D) =0x01D4C0(H), Downlink Payload: 07 01 01 D4 C0  ~-~-->  AT+3V3T=120000

1182 * 80s=80000ms(D) =0x013880(H), Downlink Payload: 07 03 01 38 80  ~-~-->  AT+12VT=80000

1412 Test the current values at the depth of different liquids and convert them to a linear scale.
1413 Replace its ratio with the ratio of water to current in the decoder.
1414
1415 Example:
1416
1417 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1418
1419 Calculate scale factor:
1420 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1421
1422 Calculation formula:
1423
1424 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1425
1426 Actual calculations:
1427
1428 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
