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.

696 1. Configure LSPH01 via AT Command or LoRaWAN Downlink
697
698 Use can configure LSPH01 via AT Command or LoRaWAN Downlink.
699
700 * AT Command Connection: See [[FAQ>>path:#AT_COMMAND]].
701 * LoRaWAN Downlink instruction for different platforms:
702

704
705
706 There are two kinds of commands to configure LSPH01, they are:
707
708 * **General Commands**.
709
710 These commands are to configure:
711
712 * General system settings like: uplink interval.
713 * LoRaWAN protocol & radio related command.
714
715 They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:
716
717 [[http:~~/~~/wiki.dragino.com/index.pHp?title=End_Device_Downlink_Command>>url:http://wiki.dragino.com/index.php?title=End_Device_Downlink_Command]]

888 1. Battery & How to replace
889 11. Battery Type
890
891 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.
892
893
894 The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

897
898
899 Minimum Working Voltage for the LSPH01:
900
901 LSPH01:  2.45v ~~ 3.6v
902
903
904 1.
905 11. Replace Battery
906
907 Any battery with range 2.45 ~~ 3.6v can be a replacement. We recommend to use Li-SOCl2 Battery.
908
909 And make sure the positive and negative pins match.
910
911
912
913 1.
914 11. Power Consumption Analyze
915
916 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.
917
918
919 Instruction to use as below:
920
921
922 Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:
923
924 [[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/]]
925
926
927 Step 2: Open it and choose
928
929 * Product Model
930 * Uplink Interval
931 * Working Mode
932
933 And the Life expectation in difference case will be shown on the right.

954 111. ​Battery Note
955
956 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.
957
958
959 1.
960 11.
961 111. ​Replace the battery
962
963 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.
964
965
966 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)

973 1. Use AT Command
974 11. Access AT Commands
975
976 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.
977
