32 The PS-LB/LS series sensors include (% style="color:blue" %)**Thread Installation Type**(%%) and (% style="color:blue" %)**Immersion Type**(%%), it supports different pressure range which can be used for different measurement requirement.
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.
301
302
303 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
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 Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.
315
316 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:
317
318 [[image:image-20230426085320-1.png||height="234" width="504"]]
319
320
321 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

342 [[image:1675144157838-392.png]]
343
344 Step 2: Activate on PS-LB/LS
345
346
347 Press the button for 5 seconds to activate the PS-LB/LS.
348
349 Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network. Green led will solidly turn on for 5 seconds after joined in network.
350
351 After join success, it will start to upload messages to TTN and you can see the messages in the panel.

357
358
359 Include device configure status. Once PS-LB/LS Joined the network, it will uplink this message to the server.
360
361 Users can also use the downlink command(0x26 01) to ask PS-LB/LS to resend this uplink.

453 === 2.3.4 Probe Model ===
454
455
456 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. 
457
458
459 For example.
460

466
467 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.
468
469
470 === 2.3.5 0~~20mA value (IDC_IN) ===
471
472
473 The output value from Pressure Probe, use together with Probe Model to get the pressure value or water level.
474
475 Example:
476
477 27AE(H) = 10158 (D)/1000 = 10.158mA.
478
479
480 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:
481
482 [[image:image-20230225154759-1.png||height="408" width="741"]]
483
484
485 === 2.3.6 0~~30V value (pin VDC_IN) ===
486
487

561
562 Step 1: Be sure that your device is programmed and properly connected to the network at this time.
563
564 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:

602
603
604 === 2.6.1 Unix TimeStamp ===
605
606
607 PS-LB uses Unix TimeStamp format based on
608
609 [[image:image-20250401163826-3.jpeg]]
610
611 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :
612
613 Below is the converter example:
614

616
617
618 === 2.6.2 Set Device Time ===
619
620
621 There are two ways to set the device's time:
622
623
624 ~1. Through LoRaWAN MAC Command (Default settings)
625
626 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
627
628 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]]].
629
630 Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
631
632
633 2. Manually Set Time
634
635 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
636
637
638 === 2.6.3 Poll sensor value ===
639
640 Users can poll sensor values based on timestamps. Below is the downlink command.

646 Timestamp end
647 )))|(% style="background-color:#f2f2f2; width:163px" %)Uplink Interval
648
649 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.
650
651 For example, downlink command[[image:image-20250117104812-1.png]]
652
653 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data

685
686 Poll Message Flag: 1: This message is a poll message reply.
687
688 * Poll Message Flag is set to 1.
689
690 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
691
692 For example, in US915 band, the max payload for different DR is:
693
694 a) DR0: max is 11 bytes so one entry of data
695
696 b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
697
698 c) DR2: total payload includes 11 entries of data
699
700 d) DR3: total payload includes 22 entries of data.
701
702 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0

1137 Format: Command Code (0x07) followed by 3 bytes.
1138
1139 The first byte is which power, the second and third bytes are the time to turn on.
1140
1141 * Example 1: Downlink Payload: 070101F4  ~-~-->  AT+3V3T=500
1142 * Example 2: Downlink Payload: 0701FFFF   ~-~-->  AT+3V3T=65535

1146 * Example 6: Downlink Payload: 07030000  ~-~-->  AT+12VT=0
1147
1148 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.
1149
1150 Therefore, the corresponding downlink command is increased by one byte to five bytes.
1151

1167 When aa=00, it is the water depth mode, and the current is converted into the water depth value; bb is the probe at a depth of several meters.
1168
1169 When aa=01, it is the pressure mode, which converts the current into a pressure value;
1170
1171 bb represents which type of pressure sensor it is.

1277
1278
1279 Test the current values at the depth of different liquids and convert them to a linear scale.
1280 Replace its ratio with the ratio of water to current in the decoder.
1281
1282 Example:
1283
1284 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1285
1286 Calculate scale factor:
1287 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1288
1289 Calculation formula:
1290
1291 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1292
1293 Actual calculations:
1294
1295 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
