44.1	12	== 1.1 What is NSPH01 Soil pH Sensor ==
10.1	13
	14	The Dragino NSPH01 is a NB-IOT 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.
	15
	16	NSPH01 probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect soil's pH with high accuracy and stable value. The NSPH01 probe can be buried into soil for long time use.
	17
	18	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.
	19	\\NSPH01 supports different uplink methods include TCP,MQTT,UDP and CoAP for different application requirement.
	20	\\NSPH01 is powered by 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)
	21	\\To use NSPH01, user needs to check if there is NB-IoT coverage in local area and with the bands NSPH01 supports. If the local operate support it, user needs to get a NB-IoT SIM card from local operator and install NSPH01 to get NB-IoT network connection.

34.1	92
44.1	93	== 2.1 How it works ==
34.1	94
	95	The NSPH01 is equipped with a NB-IoT module, the pre-loaded firmware in NSPH01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module. The NB-IoT network will forward this value to IoT server via the protocol defined by NSPH01.
	96
	97	The diagram below shows the working flow in default firmware of NSPH01:

	412	Measurement the soil surface:
	413
	414	[[image:image-20220907154700-18.png]]
	415
	416	Choose the proper measuring position. Split the surface soil according to the measured deep.
	417
	418	Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
	419
	420	Slowly insert the probe to the measure point. Don't use large force which will break the probe. Make sure not shake when inserting.
	421
	422	Put soil over the probe after insert. And start to measure.
	423
	424	Measurement inside soil:
	425
	426	Dig a hole with diameter > 20CM.
	427
	428	Insert the probe inside, method like measure the surface.
	429
44.1	430	=== 2.7.3 Maintain Probe ===
34.1	431
	432	1. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
	433	1. After long time use (3~~ 6 months). The probe electrode needs to be clean; user can use high grade sandpaper to polish it or put in 5% hydrochloric acid for several minutes. After the metal probe looks like new, user can use pure water to wash it.
	434	1. Probe reference electrode is also no strong, need to avoid strong force or hitting.
	435	1. User should keep reference electrode wet while not use.
	436	1. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
	437	1. The probe is IP68 can be put in water.

34.1	504
44.1	505	=== 2.13.1 Battery Type ===
34.1	506
	507	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.
	508
	509	The battery is designed to last for several years depends on the actually use environment and update interval.
	510

44.1	519	=== 2.13.2 Power consumption Analyze ===
34.1	520
	521	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.
	522
	523	Instruction to use as below:
	524
	525	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/]]
	526
	527	Step 2: Open it and choose
	528
	529	* Product Model
	530	* Uplink Interval
	531	* Working Mode

44.1	540	=== 2.13.3 Battery Note ===
34.1	541
	542	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.
	543
44.1	544	=== 2.13.4 Replace the battery ===
34.1	545
	546	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).
	547
