31 (((
32 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.
33 )))
34
35 (((
36 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.
37 )))
38
39 (((
40 PS-LB supports BLE configure and wireless OTA update which make user easy to use.
41 )))
42
43 (((
44 PS-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
45 )))
46
47 (((
48 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.

253
254 == 2.1 How it works ==
255
256
257 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.
258
259
260 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
261
262
263 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.
264
265
266 [[image:1675144005218-297.png]]
267
268
269 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.
270
271
272 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB.
273
274 Each PS-LB is shipped with a sticker with the default device EUI as below:
275
276 [[image:image-20230426085320-1.png||height="234" width="504"]]
277

412
413 PS-LB 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. 
414
415
416 **For example.**

423
424 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.
425
426
427 === 2.3.5 0~~20mA value (IDC_IN) ===
428
429
430 The output value from **Pressure Probe**, use together with Probe Model to get the pressure value or water level.
431
432 (% style="color:#037691" %)**Example**:
433
434 27AE(H) = 10158 (D)/1000 = 10.158mA.
435
436
437 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:
438

440
441
442 === 2.3.6 0~~30V value ( pin VDC_IN) ===
443
444
445 Measure the voltage value. The range is 0 to 30V.
446
447 (% style="color:#037691" %)**Example**:
448
449 138E(H) = 5006(D)/1000= 5.006V
450
451
452 === 2.3.7 IN1&IN2&INT pin ===
453
454
455 IN1 and IN2 are used as digital input pins.
456
457 (% style="color:#037691" %)**Example**:
458
459 09 (H): (0x09&0x08)>>3=1    IN1 pin is high level.
460
461 09 (H): (0x09&0x04)>>2=0    IN2 pin is low level.
