256
257
258 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.
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

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/LS.
274
275 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

413
414 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. 
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:

842 == 6.4 How to measure the depth of other liquids other than water? ==
843
844
845 Test the current values at the depth of different liquids and convert them to a linear scale.
846 Replace its ratio with the ratio of water to current in the decoder.
847
848 **Example:**
849
850 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
851
852 **Calculate scale factor：**
853 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
854
855 **Calculation formula：**
856
857 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
858
859 **Actual calculations：**
860
861 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
