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
22 NSPH01 supports different uplink methods include (% style="color:blue" %)**TCP,MQTT,UDP and CoAP  **(%%)for different application requirement.
23
24 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)
25
26 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.

108
109
110 == 2.1  How it works ==
111
112
113 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.
114
115 The diagram below shows the working flow in default firmware of NSPH01:

123
124
125 === 2.2.1 Test Requirement ===
126
127
128 To use NSPH01 in the field, make sure meet below requirements:
129
130 * Your local operator has already distributed a NB-IoT Network there.
131 * The local NB-IoT network used the band that NSPH01 supports.
132 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
133
134 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.

448
449 The 5V output time can be controlled by AT Command.
450
451 (% style="color:blue" %)**AT+5VT=1000**

488 The NSPH01 has an internal LED which is to show the status of different state.
489
490 * 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)
491 * Then the LED will be on for 1 second means device is boot normally.
492 * After NSPH01 join NB-IoT network. The LED will be ON for 3 seconds.
493 * For each uplink probe, LED will be on for 500ms.

497
498 === 2.7.1  Before measurement ===
499
500
501 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. 
502
503
504
505 === 2.7.2  Measurement ===

509
510
511 [[image:image-20220907154700-18.png]] ​
512
513 Choose the proper measuring position. Split the surface soil according to the measured deep.
514
515 Put pure water, or rainwater to make the soil of measurement point to moist mud. Remove rocks or hard things.
516
517 Slowly insert the probe to the measure point. Don't use large force which will break the probe. Make sure not shake when inserting.
518
519 Put soil over the probe after insert. And start to measure.
520
521
522 (% style="color:#037691" %)**Measurement inside soil:**
523
524 Dig a hole with diameter > 20CM.
525
526 Insert the probe inside, method like measure the surface.
527
528
529
530 === 2.7.3  Maintain Probe ===
531
532
533 1. pH probe electrode is fragile and no strong. User must avoid strong force or hitting it.
534 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.
535 1. Probe reference electrode is also no strong, need to avoid strong force or hitting.
536 1. User should keep reference electrode wet while not use.
537 1. Avoid the probes to touch oily matter. Which will cause issue in accuracy.
538 1. The probe is IP68 can be put in water.

625
626 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.
627
628 The battery is designed to last for several years depends on the actually use environment and update interval.

664
665
666 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.
667
668
669
670 === 2.13.4  Replace the battery ===
671
672
673 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).
