13 == 1.1 ​ What is NLMS01 Leaf Moisture Sensor ==
14
15
16 The Dragino NLMS01 is a (% style="color:blue" %)**NB-IOT Leaf Moisture Sensor**(%%) for IoT of Agriculture. It is designed to measure the leaf moisture and temperature, so to send to the platform to analyze the leaf status such as : watering, moisturizing, dew, frozen. The probe is IP67 waterproof.
17
18 NLMS01 detects leaf's(% style="color:blue" %)** moisture and temperature use FDR method**(%%), it senses the dielectric constant cause by liquid over the leaf surface, and cover the value to leaf moisture. The probe is design in a leaf shape to best simulate the real leaf characterizes. The probe has as density as 15 leaf vein lines per centimeter which make it can senses small drop and more accuracy.
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 \\NLMS01 supports different uplink methods include (% style="color:blue" %)**TCP,MQTT,UDP and CoAP  **(%%)for different application requirement.
22 \\NLMS01 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 NLMS01, user needs to check if there is NB-IoT coverage in local area and with the bands NLMS01 supports. If the local operate support it, user needs to get a (% style="color:blue" %)**NB-IoT SIM card**(%%) from local operator and install NLMS01 to get NB-IoT network connection.

109 = 2.  Use NLMS01 to communicate with IoT Server =
110
111
112 == 2.1  How it works ==
113
114
115 The NLMS01 is equipped with a NB-IoT module, the pre-loaded firmware in NLMS01 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 NLMS01.
116
117 The diagram below shows the working flow in default firmware of NLMS01:

124 == 2.2 ​ Configure the NLMS01 ==
125
126
127 === 2.2.1 Test Requirement ===
128
129
130 To use NLMS01 in your city, make sure meet below requirements:
131
132 * Your local operator has already distributed a NB-IoT Network there.
133 * The local NB-IoT network used the band that NLMS01 supports.
134 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
135
136 Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NLMS01 will use(% style="color:#037691" %)** CoAP(120.24.4.116:5683) **(%%)or raw(% style="color:#037691" %)** UDP(120.24.4.116:5601)** or(%%) (% style="color:#037691" %)**MQTT(120.24.4.116:1883)**(%%)or (% style="color:#037691" %)**TCP(120.24.4.116:5600)**(%%)protocol to send data to the test server

410
411
412 Digital Interrupt refers to pin (% style="color:#037691" %)**GPIO_EXTI**(%%), and there are different trigger methods. When there is a trigger, the NLMS01 will send a packet to the server.
413
414 The command is:

417
418 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.
419
420 Example:
421
422 0x(00): Normal uplink packet.
423
424 0x(01): Interrupt Uplink Packet.
425
426
427
428 === 2.4.9  ​+5V Output ===
429
430
431 NLMS01 will enable +5V output before all sampling and disable the +5v after all sampling. 
432
433 The 5V output time can be controlled by AT Command.
434
435 (% style="color:blue" %)**AT+5VT=1000**
436
437 Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.** **

476
477 The NLMS01 has an internal LED which is to show the status of different state.
478
479 * When power on, NLMS01 will detect if sensor probe is connected, if probe detected, LED will blink four times. (no blinks in this step is no probe)
480 * Then the LED will be on for 1 second means device is boot normally.
481 * After NLMS01 join NB-IoT network. The LED will be ON for 3 seconds.
482 * For each uplink probe, LED will be on for 500ms.

567
568
569 The NLMS01 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.
570
571 The battery is designed to last for several years depends on the actually use environment and update interval.

603 === 2.12.3  ​Battery Note ===
604
605
606 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.
607
608
609
610 === 2.12.4  Replace the battery ===
611
612
613 The default battery pack of NLMS01 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).
