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.

42
43 (((
44 PS-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery **(%%)or (% style="color:blue" %)**solar powered + Li-ion battery **(%%), it is designed for long term use up to 5 years.

47 (((
48 Each PS-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

291
292 == 2.1 How it works ==
293
294
295 The PS-LB/LS is configured as (% style="color:#037691" %)**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.
296
297
298 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
299
300
301 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.
302
303 [[image:1675144005218-297.png]]
304
305
306 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.
307
308
309 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB/LS.
310
311 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

607 === 2.6.2 Set Device Time ===
608
609
610 There are two ways to set the device's time:
611
612
613 (% style="color:blue" %)**1. Through LoRaWAN MAC Command (Default settings)**
614
615 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
616
617 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]]].
618
619 (% style="color:red" %)**Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.**
620
621
622 (% style="color:blue" %)** 2. Manually Set Time**
623
624 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
625
626
627 === 2.6.3 Poll sensor value ===
628
629 Users can poll sensor values based on timestamps. Below is the downlink command.

637
638 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.
639
640 For example, downlink command[[image:image-20250117104812-1.png]]
641
642 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data

681 **Poll Message Flag**: 1: This message is a poll message reply.
682
683 * Poll Message Flag is set to 1.
684
685 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
686
687 For example, in US915 band, the max payload for different DR is:
688
689 **a) DR0:** max is 11 bytes so one entry of data
690
691 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
692
693 **c) DR2:** total payload includes 11 entries of data
694
695 **d) DR3: **total payload includes 22 entries of data.
696
697 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0

1294
1295
1296 Test the current values at the depth of different liquids and convert them to a linear scale.
1297 Replace its ratio with the ratio of water to current in the decoder.
1298
1299 **Example:**
1300
1301 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1302
1303 **Calculate scale factor：**
1304 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1305
1306 **Calculation formula：**
1307
1308 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1309
1310 **Actual calculations：**
1311
1312 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
