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.

268

270
271
272 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.
273
274
275 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
276
277
278 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.
279
280
281 [[image:1675144005218-297.png]]
282
283
284 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.
285
286
287 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from PS-LB/LS.
288
289 Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

428 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.

856 == 6.4 How to measure the depth of other liquids other than water? ==
857
858
859 Test the current values at the depth of different liquids and convert them to a linear scale.
860 Replace its ratio with the ratio of water to current in the decoder.
861
862 **Example:**
863
864 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
865
866 **Calculate scale factor：**
867 Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
868
869 **Calculation formula：**
870
871 Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
872
873 **Actual calculations：**
874
875 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
