3.2	25	== 1.1 What is LoRaWAN Soil pH Sensor ==
2.2	26
3.2	27	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	28
3.2	29	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	30
	31	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.
	32
3.2	33	LSPH01 is powered by (% style="color:#4f81bd" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
2.2	34
3.2	35	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.

	891	11. Battery Type
	892
	893	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.
	894
	895
	896	The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

2.2	907	11. Replace Battery
	908
	909	Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.
	910
	911	And make sure the positive and negative pins match.

	914
26.5	915	1.
2.2	916	11. Power Consumption Analyze
	917
	918	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.
	919
	920
	921	Instruction to use as below:
	922
	923
	924	Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:
	925
	926	[[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/]]
	927
	928
	929	Step 2: Open it and choose
	930
	931	* Product Model
	932	* Uplink Interval
	933	* Working Mode
	934
	935	And the Life expectation in difference case will be shown on the right.

2.2	956	111. Battery Note
	957
	958	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.
	959
	960
26.5	961	1.
	962	11.
2.2	963	111. Replace the battery
	964
	965	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.
	966
	967
	968	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)
