33 )))
34
35 (((
36 The LoRa wireless technology used in PS-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
37 )))
38
39 (((
40 PS-LB/LS supports BLE configure and wireless OTA update which make user easy to use.

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
308 [[image:image-20250419162538-1.png]]
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.**
315

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

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
472 For example.
473

479
480 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.
481
482
483 === 2.3.5 0~~20mA value (IDC_IN) ===
484
485
486 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
487
488 Example:
489
490 27AE(H) = 10158 (D)/1000 = 10.158mA.
491
492
493 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:
494

496
497
498 === 2.3.6 0~~30V value (pin VDC_IN) ===
499
500
501 Measure the voltage value. The range is 0 to 30V.
502
503 Example:
504
505 138E(H) = 5006(D)/1000= 5.006V
506
507
508 === 2.3.7 IN1&IN2&INT pin ===
509
510
511 IN1 and IN2 are used as digital input pins.
512
513 Example:
514
515 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
516
517 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
518
519
520 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.
521
522 Example:
523
524 09 (H): (0x09&0x02)>>1=1    The level of the interrupt pin.
525
526 09 (H): 0x09&0x01=1              0x00: Normal uplink packet.

574
575 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
576
577 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:

615
616
617 === 2.6.1 Unix TimeStamp ===
618
619
620 PS-LB uses Unix TimeStamp format based on
621
622 [[image:image-20250401163826-3.jpeg]]
623
624 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
625
626 Below is the converter example:
627

629
630
631 === 2.6.2 Set Device Time ===
632
633
634 There are two ways to set the device's time:
635
636
637 ~1. Through LoRaWAN MAC Command (Default settings)
638
639 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
640
641 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]]].
642
643 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
644
645
646 2. Manually Set Time
647
648 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
649
650
651 === 2.6.3 Poll sensor value ===
652
653 Users can poll sensor values based on timestamps. Below is the downlink command.

659 Timestamp end
660 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
661
662 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.
663
664 For example, downlink command[[image:image-20250117104812-1.png]]
665
666 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data

699 Poll Message Flag: 1: This message is a poll message reply.
700
701 * Poll Message Flag is set to 1.
702
703 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
704
705 For example, in US915 band, the max payload for different DR is:
706
707 a) DR0: max is 11 bytes so one entry of data
708
709 b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
710
711 c) DR2: total payload includes 11 entries of data
712
713 d) DR3: total payload includes 22 entries of data.
714
715 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0

862
863 ==== 2.8.2.1 Wave alarm mode ====
864
865
866 Feature: By setting the detection period and a change value, the IDC/VDC variable is monitored whether it exceeds the set change value. If this change value is exceeded, the ROC uplink is sent and the comparison value is flushed.
867
868 * Change value: The amount by which the next detection value increases/decreases relative to the previous detection value.
869 * Comparison value: A parameter to compare with the latest ROC test.

1291
1292 Test the current values at the depth of different liquids and convert them to a linear scale.
1293 Replace its ratio with the ratio of water to current in the decoder.
1294
1295 Example:
1296
1297 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1298
1299 Calculate scale factor:
1300 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1301
1302 Calculation formula:
1303
1304 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1305
1306 Actual calculations:
1307
1308 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
