24 (((
25 The Dragino PS-LB series sensors are (% style="color:blue" %)**LoRaWAN Pressure Sensor**(%%) for Internet of Things solution. PS-LB can measure Air, Water pressure and liquid level and upload the sensor data via wireless to LoRaWAN IoT server.
26 )))
27
28 (((
29 The PS-LB 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.
30 )))
31
32 (((
33 The LoRa wireless technology used in PS-LB 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.
34 )))
35
36 (((
37 PS-LB supports BLE configure and wireless OTA update which make user easy to use.
38 )))
39
40 (((
41 PS-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
42 )))
43
44 (((
45 Each PS-LB 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.

254
255 == 2.1 How it works ==
256
257
258 The PS-LB 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. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
259
260
261 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
262
263
264 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.
265
266
267 [[image:1675144005218-297.png]]
268
269
270 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.
271
272
273 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB.
274
275 Each PS-LB is shipped with a sticker with the default device EUI as below:

415
416
417 **For example.**

424
425 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.
426
427
428 === 2.3.5 0~~20mA value (IDC_IN) ===
429
430
431 The output value from **Pressure Probe**, use together with Probe Model to get the pressure value or water level.
432
433 (% style="color:#037691" %)**Example**:
434
435 27AE(H) = 10158 (D)/1000 = 10.158mA.
436
437
438 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:

441
442
443 === 2.3.6 0~~30V value ( pin VDC_IN) ===
444
445
446 Measure the voltage value. The range is 0 to 30V.
447
448 (% style="color:#037691" %)**Example**:
449

454
455
