25
26
27 (((
28 The Dragino PS-LB/LS series sensors are (% style="color:blue" %)**LoRaWAN Pressure Sensor**(%%) for Internet of Things solution. PS-LB/LS can measure Air, Water pressure and liquid level and upload the sensor data via wireless to LoRaWAN IoT server.
29 )))
30
31 (((
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.
41 )))
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.
45 )))
46
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.

294
295 == 2.1 How it works ==
296
297
298 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.
299
300
301 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
302
303
304 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.
305
306 [[image:1675144005218-297.png]]
307
308
309 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.
310
311
312 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB/LS.
313
314 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

316 [[image:image-20230426085320-1.png||height="234" width="504"]]

610 === 2.6.2 Set Device Time ===
611
612
613 There are two ways to set the device's time:
614
615
616 (% style="color:blue" %)**1. Through LoRaWAN MAC Command (Default settings)**
617
618 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
619
620 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]]].
621
622 (% 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.**
623
624
625 (% style="color:blue" %)** 2. Manually Set Time**
626
627 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
628
629
630 === 2.6.3 Poll sensor value ===
631
632 Users can poll sensor values based on timestamps. Below is the downlink command.

641 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.
642
643 For example, downlink command[[image:image-20250117104812-1.png]]
644
645 Is to check 2024/12/20 09:34:59 to 2024/12/20 14:34:59's data

685
686 * Poll Message Flag is set to 1.
687
688 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
689
690 For example, in US915 band, the max payload for different DR is:
691
692 **a) DR0:** max is 11 bytes so one entry of data
693
694 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
695
696 **c) DR2:** total payload includes 11 entries of data
697
698 **d) DR3: **total payload includes 22 entries of data.

1297
1298
1299 Test the current values at the depth of different liquids and convert them to a linear scale.
1300 Replace its ratio with the ratio of water to current in the decoder.
1301
1302 **Example:**
1303
1304 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1305
1306 **Calculate scale factor：**
1307 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1308
1309 **Calculation formula：**
1310
1311 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1312
1313 **Actual calculations：**
1314
1315 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
