44.1	113	== 2.1 How it works ==
34.1	114
50.3	115
34.1	116	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.
	117
	118	The diagram below shows the working flow in default firmware of NSPH01:

44.1	357	=== 2.4.8 Digital Interrupt ===
34.1	358
	359	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.
	360
	361	The command is:
	362
	363	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]]).
	364
	365	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.
	366
	367	Example:
	368
	369	0x(00): Normal uplink packet.
	370
	371	0x(01): Interrupt Uplink Packet.
	372
44.1	373	=== 2.4.9 +5V Output ===
34.1	374
	375	NSPH01 will enable +5V output before all sampling and disable the +5v after all sampling.
	376
	377	The 5V output time can be controlled by AT Command.
	378
	379	AT+5VT=1000
	380
	381	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	382
	383
44.1	384	== 2.5 Downlink Payload ==

44.1	426	=== 2.7.1 Before measurement ===
34.1	427
	428	If the NSPH01 has more than 7 days not use or just clean the pH probe. User should put the probe inside pure water for more than 24 hours for activation. If no put in water, user need to put inside soil for more than 24 hours to ensure the measurement accuracy.
	429
44.1	430	=== 2.7.2 Measurement ===
34.1	431
	432	Measurement the soil surface:
	433
	434	[[image:image-20220907154700-18.png]]
	435
	436	Choose the proper measuring position. Split the surface soil according to the measured deep.
	437
	438	Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
	439
	440	Slowly insert the probe to the measure point. Don't use large force which will break the probe. Make sure not shake when inserting.
	441
	442	Put soil over the probe after insert. And start to measure.
	443
	444	Measurement inside soil:
	445
	446	Dig a hole with diameter > 20CM.
	447
	448	Insert the probe inside, method like measure the surface.
	449
44.1	450	=== 2.7.3 Maintain Probe ===
34.1	451
	452	1. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
	453	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.
	454	1. Probe reference electrode is also no strong, need to avoid strong force or hitting.
	455	1. User should keep reference electrode wet while not use.
	456	1. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
	457	1. The probe is IP68 can be put in water.

44.1	523	== 2.13 Battery Analysis ==
34.1	524
44.1	525	=== 2.13.1 Battery Type ===
34.1	526
	527	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.
	528
	529	The battery is designed to last for several years depends on the actually use environment and update interval.
	530

44.1	539	=== 2.13.2 Power consumption Analyze ===
34.1	540
	541	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.
	542
	543	Instruction to use as below:
	544
	545	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/]]
	546
	547	Step 2: Open it and choose
	548
	549	* Product Model
	550	* Uplink Interval
	551	* Working Mode
	552
	553	And the Life expectation in difference case will be shown on the right.

	559
44.1	560	=== 2.13.3 Battery Note ===
34.1	561
	562	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.
	563
44.1	564	=== 2.13.4 Replace the battery ===
34.1	565
	566	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).
	567
