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.

256
257 == 2.1 How it works ==
258
259
260 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.
261
262
263 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
264
265
266 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.
267
268
269 [[image:1675144005218-297.png]]
270
271
272 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.
273
274
275 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB/LS.
276
277 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

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

415
416 PS-LB/LS has different kind of probe, 4~~20mA represent the full scale of the measuring range. So a 12mA output means different meaning for different probe. 
417
418
419 **For example.**

426
427 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.
428
429
430 === 2.3.5 0~~20mA value (IDC_IN) ===
431
432
433 The output value from **Pressure Probe**, use together with Probe Model to get the pressure value or water level.
434
435 (% style="color:#037691" %)**Example**:
436
437 27AE(H) = 10158 (D)/1000 = 10.158mA.
438
439
440 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:
