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.

	881	11. Battery Type
	882
	883	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.
	884
	885
	886	The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

24.2	896	1.
2.2	897	11. Replace Battery
	898
	899	Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.
	900
	901	And make sure the positive and negative pins match.
	902

	904
24.2	905	1.
2.2	906	11. Power Consumption Analyze
	907
	908	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.
	909
	910
	911	Instruction to use as below:
	912
	913
	914	Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:
	915
	916	[[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/]]
	917
	918
	919	Step 2: Open it and choose
	920
	921	* Product Model
	922	* Uplink Interval
	923	* Working Mode
	924
	925	And the Life expectation in difference case will be shown on the right.

2.2	946	111. Battery Note
	947
	948	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.
	949
	950
24.2	951	1.
	952	11.
2.2	953	111. Replace the battery
	954
	955	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.
	956
	957
	958	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)
	959
	960
	961
	962
	963
	964
	965	1. Use AT Command
	966	11. Access AT Commands
	967
	968	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.
