44.1	12	== 1.1 What is NSPH01 Soil pH Sensor ==
10.1	13
46.1	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.
10.1	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.
46.1	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 the installation area and with the bands NSPH01 supports. If the local operator supports 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:

	331	Digital Interrupt refers to pin GPIO_EXTI, and there are different trigger methods. When there is a trigger, the NSPH01 will send a packet to the server.
	332
	333	The command is:
	334
	335	AT+INTMOD=3 ~/~/(more info about INMOD please refer [[AT Command Manual>>url:https://www.dragino.com/downloads/downloads/NB-IoT/NBSN95/DRAGINO_NBSN95-NB_AT%20Commands_v1.1.0.pdf]]).
	336
	337	The lower four bits of this data field shows if this packet is generated by interrupt or not. Click here for the hardware and software set up.
	338
	339	Example:
	340
	341	0x(00): Normal uplink packet.
	342
	343	0x(01): Interrupt Uplink Packet.
	344
44.1	345	=== 2.4.9 +5V Output ===
34.1	346
	347	NSPH01 will enable +5V output before all sampling and disable the +5v after all sampling.
	348
	349	The 5V output time can be controlled by AT Command.
	350
	351	AT+5VT=1000
	352
	353	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	354

	386
44.1	387	== 2.6 LED Indicator ==
34.1	388
	389	The NSPH01 has an internal LED which is to show the status of different state.
	390
	391	* When power on, NSPH01 will detect if sensor probe is connected, if probe detected, LED will blink four times. (no blinks in this step is no probe)
	392	* Then the LED will be on for 1 second means device is boot normally.

	406	[[image:image-20220907154700-18.png]]
	407
	408	Choose the proper measuring position. Split the surface soil according to the measured deep.
	409
	410	Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
	411
	412	Slowly insert the probe to the measure point. Don't use large force which will break the probe. Make sure not shake when inserting.
	413
	414	Put soil over the probe after insert. And start to measure.
	415
	416	Measurement inside soil:
	417
	418	Dig a hole with diameter > 20CM.
	419
	420	Insert the probe inside, method like measure the surface.

34.1	423
	424	1. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
	425	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.
	426	1. Probe reference electrode is also no strong, need to avoid strong force or hitting.
	427	1. User should keep reference electrode wet while not use.
	428	1. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
	429	1. The probe is IP68 can be put in water.

34.1	496
44.1	497	=== 2.13.1 Battery Type ===
34.1	498
	499	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.
	500
	501	The battery is designed to last for several years depends on the actually use environment and update interval.
	502

44.1	511	=== 2.13.2 Power consumption Analyze ===
34.1	512
	513	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.
	514
	515	Instruction to use as below:
	516
	517	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/]]
	518
	519	Step 2: Open it and choose
	520
	521	* Product Model
	522	* Uplink Interval
	523	* Working Mode
	524
	525	And the Life expectation in difference case will be shown on the right.

	531
44.1	532	=== 2.13.3 Battery Note ===
34.1	533
	534	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.
	535
44.1	536	=== 2.13.4 Replace the battery ===
34.1	537
	538	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).
	539
