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.

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:
312
313 [[image:image-20230426085320-1.png||height="234" width="504"]]

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

806 == 3.1 Configure Methods ==
807
808
809 PS-LB/LS supports below configure method:
810
811 * AT Command via Bluetooth Connection (**Recommand Way**): [[BLE Configure Instruction>>url:http://wiki.dragino.com/xwiki/bin/view/Main/BLE%20Bluetooth%20Remote%20Configure/]].
812 * AT Command via UART Connection : See [[FAQ>>||anchor="H6.FAQ"]].
813 * LoRaWAN Downlink.  Instruction for different platforms: See [[IoT LoRaWAN Server>>url:http://wiki.dragino.com/xwiki/bin/view/Main/]] section.
814
815 == 3.2 General Commands ==
816
817
818 These commands are to configure:
819
820 * General system settings like: uplink interval.
821 * LoRaWAN protocol & radio related command.
822
823 They are same for all Dragino Devices which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:

1091
1092
1093 Test the current values at the depth of different liquids and convert them to a linear scale.
1094 Replace its ratio with the ratio of water to current in the decoder.
1095
1096 **Example:**
1097
1098 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1099
1100 **Calculate scale factor：**
1101 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1102
1103 **Calculation formula：**
1104
1105 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1106
