16 (((
17 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.
18
19 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.
20
21 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.
22
23 NLMS01 supports different uplink methods include (% style="color:blue" %)**TCP,MQTT,UDP and CoAP  **(%%)for different application requirement.
24
25 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).
26
27 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.

117
118
119 == 2.1  How it works ==
120
121
122 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.
123
124 The diagram below shows the working flow in default firmware of NLMS01:

131 == 2.2 ​ Configure the NLMS01 ==
132
133
134 === 2.2.1 Test Requirement ===
135
136
137 To use NLMS01 in your city, make sure meet below requirements:
138
139 * Your local operator has already distributed a NB-IoT Network there.
140 * The local NB-IoT network used the band that NLMS01 supports.
141 * Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
142
143 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

451 The 5V output time can be controlled by AT Command.
452
453 (% style="color:blue" %)**AT+5VT=1000**

495 The NLMS01 has an internal LED which is to show the status of different state.
496
497 * 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)
498 * Then the LED will be on for 1 second means device is boot normally.
499 * After NLMS01 join NB-IoT network. The LED will be ON for 3 seconds.
500 * For each uplink probe, LED will be on for 500ms.

583
584
585 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.
586
587 The battery is designed to last for several years depends on the actually use environment and update interval.

619 === 2.12.3  ​Battery Note ===
620
621
622 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.
623
624
625
626 === 2.12.4  Replace the battery ===
627
628
629 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).
