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.

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.

688 1. Configure LSPH01 via AT Command or LoRaWAN Downlink
689
690 Use can configure LSPH01 via AT Command or LoRaWAN Downlink.
691
692 * AT Command Connection: See [[FAQ>>path:#AT_COMMAND]].
693 * LoRaWAN Downlink instruction for different platforms:
694
695 [[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]]
696
697
698 There are two kinds of commands to configure LSPH01, they are:
699
700 * **General Commands**.
701
702 These commands are to configure:
703
704 * General system settings like: uplink interval.
705 * LoRaWAN protocol & radio related command.
706
707 They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:
708
709 [[http:~~/~~/wiki.dragino.com/index.pHp?title=End_Device_Downlink_Command>>url:http://wiki.dragino.com/index.php?title=End_Device_Downlink_Command]]

880 1. Battery & How to replace
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.

889
890
891 Minimum Working Voltage for the LSPH01:
892
893 LSPH01:  2.45v ~~ 3.6v
894
895
896 1.
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
903
904
905 1.
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.

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
951 1.
952 11.
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)

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.
969

1001
1002 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.
