13 == 1.1 ​ What is NSPH01 Soil pH Sensor ==
14
15
16 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.
17
18 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.
19
20 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.
21 \\NSPH01 supports different uplink methods include (% style="color:blue" %)**TCP,MQTT,UDP and CoAP  **(%%)for different application requirement.
22 \\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)
23 \\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.

99 = 2.  Use NSPH01 to communicate with IoT Server =
100
101
102 == 2.1  How it works ==
103
104
105 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.
106
107 The diagram below shows the working flow in default firmware of NSPH01:

114 == 2.2 ​ Configure the NSPH01 ==
115
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 === 2.2.3 Connect USB – TTL to NSPH01 to configure it ===
143
144
145 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.

310
311
312 **Example:**
313
314 AT+DEUI=868411056754138
315
316 The Device ID is stored in a none-erase area, Upgrade the firmware or run AT+FDR won't erase Device ID.
317
318
319
320 === 2.4.2  Version Info ===
321
322
323 Specify the software version: 0x64=100, means firmware version 1.00.
324
325 For example: 0x00 64 : this device is NSPH01 with firmware version 1.0.0.
326
327
328
329 === 2.4.3  Battery Info ===
330

356
357
358
359 === 2.4.5  Soil PH ===
360
361
362 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.
363
364 For example, if the data you get from the register is **__0x05 0xDC__**, the PH content in the soil is
365
366 **0229(H) = 549(D) /100 = 5.49.**
367
368
369
370 === 2.4.6  Soil Temperature ===
371
372
373 Get the temperature in the soil. The value range of the register is -4000 - +800(Decimal), divide this value by 100 to get the temperature in the soil. For example, if the data you get from the register is **__0x09 0xEC__**, the temperature content in the soil is
374
375 **Example**:
376
377 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/10 = 26.1 °C
378
379 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/10 = -12.9 °C

391
392 === 2.4.8  Digital Interrupt ===
393
394
395 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.
396
397 The command is:
398
399 (% 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]])**.**
400
401 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.
402
403 Example:
404
405 0x(00): Normal uplink packet.
406
407 0x(01): Interrupt Uplink Packet.
408
409
410
411 === 2.4.9  ​+5V Output ===
412
413
414 NSPH01 will enable +5V output before all sampling and disable the +5v after all sampling. 
415
416 The 5V output time can be controlled by AT Command.
417
418 (% style="color:blue" %)**AT+5VT=1000**
419
420 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.** **
421
422
423
424 == 2.5  Downlink Payload ==
425
426
427 By default, NSPH01 prints the downlink payload to console port.

432 (% style="color:blue" %)**Examples:**
433
434 * (% style="color:#037691" %)** Set TDC**
435
436 If the payload=0100003C, it means set the END Node's TDC to 0x00003C=60(S), while type code is 01.
437
438 Payload:    01 00 00 1E    TDC=30S

455 The NSPH01 has an internal LED which is to show the status of different state.
456
457 * 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)
458 * Then the LED will be on for 1 second means device is boot normally.
459 * After NSPH01 join NB-IoT network. The LED will be ON for 3 seconds.
460 * For each uplink probe, LED will be on for 500ms.

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.

481 [[image:image-20220907154700-18.png]] ​
482
483 Choose the proper measuring position. Split the surface soil according to the measured deep.
484
485 Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
486
487 Slowly insert the probe to the measure point. Don't use large force which will break the probe. Make sure not shake when inserting.
488
489 Put soil over the probe after insert. And start to measure.

500 === 2.7.3  Maintain Probe ===
501
502
503 1. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
504 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.
505 1. Probe reference electrode is also no strong, need to avoid strong force or hitting.
506 1. User should keep reference electrode wet while not use.
507 1. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
508 1. The probe is IP68 can be put in water.

598 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.
599
600 The battery is designed to last for several years depends on the actually use environment and update interval.

635 === 2.13.3  ​Battery Note ===
636
637
638 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.
639
640
641
642 === 2.13.4  Replace the battery ===
643
644
645 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).
