3.2	20	== 1.1 What is LoRaWAN Soil pH Sensor ==
2.2	21
3.2	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.
2.2	23
3.2	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.
2.2	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
3.2	28	LSPH01 is powered by (% style="color:#4f81bd" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
2.2	29
3.2	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.

2.2	88	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.

	293	Step 1: Be sure that your device is programmed and properly connected to the network at this time.
	294
	295	Step 2: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:

	342	111. Before measurement
	343
3.2	344	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.

2.2	349	111. Measurement
	350
	351	Measurement the soil surface
	352
	353
	354	[[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.
	355
	356
	357	Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
	358
	359
	360	Slowly insert the probe to the measure point. Don’t use large force which will break the probe. Make sure not shake when inserting.
	361
	362
	363	Put soil over the probe after insert. And start to measure.
	364
	365
	366	Measurement inside soil
	367
	368
	369
	370	Dig a hole with diameter > 20CM.
	371
	372
	373	Insert the probe inside, method like measure the surface.
	374
	375
14.4	376	1.
	377	11.
2.2	378	111. Maintain Probe
	379	1111. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
	380	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.
	381	1111. Probe reference electrode is also no strong, need to avoid strong force or hitting.
	382	1111. User should keep reference electrode wet while not use.
	383	1111. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
	384	1111. The probe is IP68 can be put in water.
	385
14.4	386	1.
2.2	387	11. Calibration
	388
	389	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).
	390
	391
	392	After stable, user can use below command to calibrate.

	899	11. Battery Type
	900
	901	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.
	902
	903
	904	The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

2.2	915	11. Replace Battery
	916
	917	Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.
	918
	919	And make sure the positive and negative pins match.
	920

	922
14.4	923	1.
2.2	924	11. Power Consumption Analyze
	925
	926	Dragino Battery powered product are all runs in Low Power mode. We have an update battery calculator which base on the measurement of the real device. User can use this calculator to check the battery life and calculate the battery life if want to use different transmit interval.
	927
	928
	929	Instruction to use as below:
	930
	931
	932	Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:
	933
	934	[[https:~~/~~/www.dragino.com/downloads/index.pHp?dir=LoRa_End_Node/Battery_Analyze/>>url:https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/Battery_Analyze/]]
	935
	936
	937	Step 2: Open it and choose
	938
	939	* Product Model
	940	* Uplink Interval
	941	* Working Mode
	942
	943	And the Life expectation in difference case will be shown on the right.

2.2	964	111. Battery Note
	965
	966	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.
	967
	968
14.4	969	1.
	970	11.
2.2	971	111. Replace the battery
	972
	973	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.
	974
	975
	976	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)
	977
	978
	979
	980
	981
	982
	983	1. Use AT Command
	984	11. Access AT Commands
	985
	986	LSPH01 supports AT Command set in the stock firmware. You can use a USB to TTL adapter to connect to LSPH01 for using AT command, as below.
