12 == 1.1 ​ What is NSPH01 Soil pH Sensor ==
13
14
15 The Dragino NSPH01 is a (% style="color:blue" %)**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.
16
17 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.
18
19 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.
20
21 NSPH01 supports different uplink methods include (% style="color:blue" %)**TCP,MQTT,UDP and CoAP  **(%%)for different application requirement.
22
23 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)
24
25 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 (% style="color:blue" %)**NB-IoT SIM card** (%%)from local operator and install NSPH01 to get NB-IoT network connection.

101 = 2.  Use NSPH01 to communicate with IoT Server =
102
103 == 2.1  How it works ==
104
105
106 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.
107
108 The diagram below shows the working flow in default firmware of NSPH01:

115 == 2.2 ​ Configure the NSPH01 ==
116
117 === 2.2.1 Test Requirement ===
118
119
120 To use NSPH01 in the field, make sure meet below requirements:
121
122 * Your local operator has already distributed a NB-IoT Network there.
123 * The local NB-IoT network used the band that NSPH01 supports.
124 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
125
126 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NSPH01 will use** CoAP(120.24.4.116:5683) **or raw **UDP(120.24.4.116:5601)** or **MQTT(120.24.4.116:1883)**or **TCP(120.24.4.116:5600)**protocol to send data to the test server.

142
143
144 User need to configure NSPH01 via serial port to set the (% style="color:blue" %)**Server Address** / **Uplink Topic**(%%) to define where and how-to uplink packets. NSPH01 support AT Commands, user can use a USB to TTL adapter to connect to NSPH01 and use AT Commands to configure it, as below.

370 Get the PH content of the soil. The value range of the register is 300-1000(Decimal), divide this value by 100 to get the percentage of PH in the soil.
371
372 For example, if the data you get from the register is (% style="color:blue" %)**__0x05 0xDC__**(%%), the PH content in the soil is
373
374 (% style="color:blue" %)**0229(H) = 549(D) /100 = 5.49.**
375

398 === 2.4.8  Digital Interrupt ===
399
400
401 Digital Interrupt refers to pin (% style="color:blue" %)**GPIO_EXTI**(%%), and there are different trigger methods. When there is a trigger, the NSPH01 will send a packet to the server.
402
403 The command is:

405 (% style="color:blue" %)**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]])**.**
406
407 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.
408
409
410 **Example:**
411
412 0x(00): Normal uplink packet.
413
414 0x(01): Interrupt Uplink Packet.
415
416
417 === 2.4.9  ​+5V Output ===
418
419
420 NSPH01 will enable +5V output before all sampling and disable the +5v after all sampling. 
421
422 The 5V output time can be controlled by AT Command.
423
424 (% style="color:blue" %)**AT+5VT=1000**
425
426 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.** **

457
458
459 The NSPH01 has an internal LED which is to show the status of different state.
460
461 * 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)
462 * Then the LED will be on for 1 second means device is boot normally.
463 * After NSPH01 join NB-IoT network. The LED will be ON for 3 seconds.
464 * For each uplink probe, LED will be on for 500ms.

467
468 === 2.7.1  Before measurement ===
469
470
471 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. 
472

478
479
480 [[image:image-20220907154700-18.png]] ​
481
482 Choose the proper measuring position. Split the surface soil according to the measured deep.
483
484 Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
485
486 Slowly insert the probe to the measure point. Don't use large force which will break the probe. Make sure not shake when inserting.
487
488 Put soil over the probe after insert. And start to measure.
489
490
491 (% style="color:#037691" %)**Measurement inside soil:**
492
493 Dig a hole with diameter > 20CM.
494
495 Insert the probe inside, method like measure the surface.
496
497
498 === 2.7.3  Maintain Probe ===
499
500
501 1. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
502 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.
503 1. Probe reference electrode is also no strong, need to avoid strong force or hitting.
504 1. User should keep reference electrode wet while not use.
505 1. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
506 1. The probe is IP68 can be put in water.

566
567 User can do calibration for the probe. It is limited to use below pH buffer solution to calibrate: 4.00, 6.86, 9.18. When calibration, user need to clean the electrode and put the probe in the pH buffer solution to wait the value stable ( a new clean electrode might need max 24 hours to be stable).
568
569 After stable, user can use below command to calibrate.

709 NSPH01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at [[this link>>url:https://www.dragino.com/downloads/downloads/LoRa_End_Node/LSE01/Calibrate_to_other_Soil_20220605.pdf]].
