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

88 = 2. Configure LSPH01 to connect to LoRaWAN network =
89
90 == 2.1 How it works ==
91
92 (((
93 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.
94 )))
95
96 (((
97 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.

698 1. Configure LSPH01 via AT Command or LoRaWAN Downlink
699
700 Use can configure LSPH01 via AT Command or LoRaWAN Downlink.
701
702 * AT Command Connection: See [[FAQ>>path:#AT_COMMAND]].
703 * LoRaWAN Downlink instruction for different platforms:
704
705 [[http:~~/~~/wiki.dragino.com/index.pHp?title=Main_Page#Use_Note_for_Server>>url:http://wiki.dragino.com/index.php?title=Main_Page#Use_Note_for_Server]]
706
707
708 There are two kinds of commands to configure LSPH01, they are:
709
710 * **General Commands**.
711
712 These commands are to configure:
713
714 * General system settings like: uplink interval.
715 * LoRaWAN protocol & radio related command.
716
717 They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:
718
719 [[http:~~/~~/wiki.dragino.com/index.pHp?title=End_Device_Downlink_Command>>url:http://wiki.dragino.com/index.php?title=End_Device_Downlink_Command]]

890 1. Battery & How to replace
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.

901 Minimum Working Voltage for the LSPH01:
902
903 LSPH01:  2.45v ~~ 3.6v
904
905
906 1.
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.
912
913
914
915 1.
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.

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
961 1.
962 11.
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)

972
973
974
975 1. Use AT Command
976 11. Access AT Commands
977
978 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.
979
980 [[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image025.png]]

1011
1012 In the case if user can see the console output but can’t type input to the device. Please check if you already include the **ENTER** while sending out the command. Some serial tool doesn’t send **ENTER** while press the send key, user need to add ENTER in their string.
