20 == 1.1 ​What is LoRaWAN Soil pH Sensor ==
21
22 The Dragino LSPH01 is a (% style="color:#4f81bd" %)**LoRaWAN Soil pH Sensor**(%%) for IoT of Agriculture. It is designed to measure the soil PH and soil temperature, so to send to the platform to analyze the soil acid or alkali level. The probe is IP68 waterproof.
23
24 LSPH01 probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect soil's** (% style="color:#4f81bd" %)pH (%%)**with high accuracy and stable value. The LSPH01 probe can be buried into soil for long time use.
25
26 The LoRa wireless technology used in LSPH01 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.
27
28 LSPH01 is powered by (% style="color:#4f81bd" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
29
30 Each LSPH01 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.

87 = 2. Configure LSPH01 to connect to LoRaWAN network =
88
89 == 2.1 How it works ==
90
91 (((
92 The LSPH01 is configured as 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 power on the LSPH01. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
93 )))
94
95 (((
96 In case you can’t set the OTAA keys in the LoRaWAN OTAA server, and you have to use the keys from the server, you can [[use AT Commands >>||anchor="H5.200BUseATCommand"]]to set the keys in the LSPH01.

361 11. Installation and Maintain
362 111. Before measurement
363
364 If the LSPH01 has more than 7 days not use or just clean the pH probe. User should put the probe inside pure water for more than 24 hours for activation. If no put in water, user need to put inside soil for more than 24 hours to ensure the measurement accuracy. 
365

371 **Measurement the soil surface**
372
373
374 [[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image021.png]] Choose the proper measuring position. Split the surface soil according to the measured deep.
375
376
377 Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
378
379
380 Slowly insert the probe to the measure point. Don’t use large force which will break the probe. Make sure not shake when inserting.
381
382
383 Put soil over the probe after insert. And start to measure.
384
385
386 **Measurement inside soil**
387
388
389
390 Dig a hole with diameter > 20CM.

397 11.
398 111. Maintain Probe
399 1111. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
400 1111. After long time use (3~~ 6  months). The probe electrode needs to be clean; user can use high grade sandpaper to polish it or put in 5% hydrochloric acid for several minutes. After the metal probe looks like new, user can use pure water to wash it.
401 1111. Probe reference electrode is also no strong, need to avoid strong force or hitting.
402 1111. User should keep reference electrode wet while not use.
403 1111. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
404 1111. The probe is IP68 can be put in water.
405
406 1.
407 11. Calibration
408
409 User can do calibration for the probe. It is limited to use below pH buffer solution to calibrate: 4.00, 6.86, 9.18. When calibration, user need to clean the electrode and put the probe in the pH buffer solution to wait the value stable ( a new clean electrode might need max 24 hours to be stable).
410
411
412 **After stable, user can use below command to calibrate.**

521 To make sure the end node supports all sub band by default. In the OTAA Join process, the end node will use frequency 1 from sub-band1, then frequency 1 from sub-band2, then frequency 1 from sub-band3, etc to process the OTAA join.
522
523
524 After Join success, the end node will switch to the correct sub band by:
525
526 * Check what sub-band the LoRaWAN server ask from the OTAA Join Accept message and switch to that sub-band
527 * Use the Join successful sub-band if the server doesn’t include sub-band info in the OTAA Join Accept message ( TTN v2 doesn't include)

581
582 To make sure the end node supports all sub band by default. In the OTAA Join process, the end node will use frequency 1 from sub-band1, then frequency 1 from sub-band2, then frequency 1 from sub-band3, etc to process the OTAA join.
583
584
585 After Join success, the end node will switch to the correct sub band by:
586
587 * Check what sub-band the LoRaWAN server ask from the OTAA Join Accept message and switch to that sub-band
588 * Use the Join successful sub-band if the server doesn’t include sub-band info in the OTAA Join Accept message ( TTN v2 doesn't include)

918 1. Battery & How to replace
919 11. Battery Type
920
921 LSPH01 is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is un-rechargeable battery with low discharge rate targeting for 8~~10 years use. This type of battery is commonly used in IoT target for long-term running, such as water meter.
922
923
924 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

984 111. ​Battery Note
985
986 The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.
987
988
989 1.
990 11.
991 111. ​Replace the battery
992
993 You can change the battery in the LSPH01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
994
995
996 The default battery pack of LSPH01 includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)
