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-on 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.

292
293
294 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.
295
296
297 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
298
299
300 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.
301
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:

878 == 6.4 How to measure the depth of other liquids other than water? ==
879
880
881 Test the current values at the depth of different liquids and convert them to a linear scale.
882 Replace its ratio with the ratio of water to current in the decoder.
883
884 **Example:**
885
886 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
887
888 **Calculate scale factor：**
889 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
890
891 **Calculation formula：**
892
893 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
894
895 **Actual calculations：**
896
897 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
