111 -
112 -
113 -== 2.1  How it works ==
114 -
115 -
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:

126 -
127 -
128 -=== 2.2.1 Test Requirement ===
129 -
130 -
131 -To use NSPH01 in the field, make sure meet below requirements:
132 -
133 -* Your local operator has already distributed a NB-IoT Network there.
134 -* The local NB-IoT network used the band that NSPH01 supports.
135 -* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
136 -
137 -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.

153 -=== 2.2.3 Connect USB – TTL to NSPH01 to configure it ===
154 -
155 -User need to configure NSPH01 via serial port to set the **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.
156 -
157 -**Connection:**
158 -
159 - USB TTL GND <~-~-~-~-> GND
160 -
161 - USB TTL TXD <~-~-~-~-> UART_RXD
162 -
163 - USB TTL RXD <~-~-~-~-> UART_TXD

166 -
167 -* Baud:  **9600**
168 -* Data bits:** 8**
169 -* Stop bits: **1**
170 -* Parity:  **None**
171 -* Flow Control: **None**
172 -
173 -Make sure the switch is in FLASH position, then power on device by connecting the jumper on NSPH01. NSPH01 will output system info once power on as below, we can enter the **password: 12345678** to access AT Command input.

333 -=== 2.4.5  Soil PH ===
334 -
335 -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.
336 -
337 -For example, if the data you get from the register is **__0x05 0xDC__**, the PH content in the soil is
338 -
339 -**0229(H) = 549(D) /100 = 5.49.**
340 -
341 -=== 2.4.6  Soil Temperature ===
342 -
343 -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
344 -
345 -**Example**:
346 -
347 -If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/10 = 26.1 °C
348 -
349 -If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/10 = -12.9 °C

356 -
357 -=== 2.4.8  Digital Interrupt ===
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 -
373 -=== 2.4.9  ​+5V Output ===
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 -
384 -== 2.5  Downlink Payload ==
385 -
386 -By default, NSPH01 prints the downlink payload to console port.

415 -== 2.6  ​LED Indicator ==
416 -
417 -The NSPH01 has an internal LED which is to show the status of different state.
418 -
419 -* 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)
420 -* Then the LED will be on for 1 second means device is boot normally.
421 -* After NSPH01 join NB-IoT network. The LED will be ON for 3 seconds.
422 -* For each uplink probe, LED will be on for 500ms.
423 -
424 -== 2.7 Installation and Maintain ==
425 -
426 -=== 2.7.1 Before measurement ===
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 -
430 -=== 2.7.2 Measurement ===
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 -
450 -=== 2.7.3 Maintain Probe ===
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.

524 -
525 -=== 2.13.1  ​Battery Type ===
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 -

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/]]

560 -=== 2.13.3  ​Battery Note ===
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 -
564 -=== 2.13.4  Replace the battery ===
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).

672 -**Notice, **NSPH01 **and **NSPH01 **share the same mother board. They use the same connection and method to update.**
673 -
674 -== 5.2  Can I calibrate NSPH01 to different soil types? ==
675 -
676 -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]].
