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.

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.

353 11. Installation and Maintain
354 111. Before measurement
355
356 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. 
357
358

361 111. Measurement
362
363 **Measurement the soil surface**
364
365
366 [[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.
367
368
369 Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
370
371
372 Slowly insert the probe to the measure point. Don’t use large force which will break the probe. Make sure not shake when inserting.
373
374
375 Put soil over the probe after insert. And start to measure.
376
377
378 **Measurement inside soil**
379
380
381
382 Dig a hole with diameter > 20CM.

389 11.
390 111. Maintain Probe
391 1111. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
392 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.
393 1111. Probe reference electrode is also no strong, need to avoid strong force or hitting.
394 1111. User should keep reference electrode wet while not use.
395 1111. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
396 1111. The probe is IP68 can be put in water.
397
398 1.
399 11. Calibration
400
401 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).
402
403
404 **After stable, user can use below command to calibrate.**

513 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.
514
515
516 After Join success, the end node will switch to the correct sub band by:
517
518 * Check what sub-band the LoRaWAN server ask from the OTAA Join Accept message and switch to that sub-band
519 * 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)

573
574 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.
575
576
577 After Join success, the end node will switch to the correct sub band by:
578
579 * Check what sub-band the LoRaWAN server ask from the OTAA Join Accept message and switch to that sub-band
580 * 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)

912
913 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.
914
915
916 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

976 111. ​Battery Note
977
978 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.
979
980
981 1.
982 11.
983 111. ​Replace the battery
984
985 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.
986
987
988 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)
