  NSPH01 probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect soil's** (% style="color:blue" %)pH (%%)**with high accuracy and stable value. The NSPH01 probe can be buried into soil for long time use.
  NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.

--\\NSPH01 is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)

--== 2.13  Battery Analysis ==
++NSPH01 uses ER26500 + SPC1520 battery pack. See below link for detail information about the battery info and how to replace.
--=== 2.13.1  Battery Type ===
++[[**Battery Info & Power Consumption Analyze**>>url:http://wiki.dragino.com/xwiki/bin/view/Main/How%20to%20calculate%20the%20battery%20life%20of%20Dragino%20sensors%3F/]] .
--The NSPH01 battery is a combination of an 8500mAh Li/SOCI2 Battery and a Super Capacitor. The battery is none-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
--
--The battery is designed to last for several years depends on the actually use environment and update interval.

--=== 2.13.2  Power consumption Analyze ===
--
--
--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.
--
--Instruction to use as below:
--
--**(% style="color:blue" %)Step 1:  **(%%)Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from: [[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/]]

--* Uplink Interval
--* Working Mode

--=== 2.13.3  Battery Note ===
--
--
--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.
--
--
--
--=== 2.13.4  Replace the battery ===
--
--
--The default battery pack of NSPH01 includes a ER26500 plus super capacitor. If user can't find this pack locally, they can find ER26500 or equivalence without the SPC1520 capacitor, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes).
