12 == 1.1 ​What is NLMS01 Leaf Moisture Sensor ==
13
14
15 The Dragino NLMS01 is a **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.
16
17 NLMS01 detects leaf's** 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.
18
19 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.
20 \\NLMS01 supports different uplink methods include **TCP,MQTT,UDP and CoAP  **for different application requirement.
21 \\NLMS01 is powered by  **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)
22 \\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 **NB-IoT SIM card** from local operator and install NLMS01 to get NB-IoT network connection

117 = 2.  Use NLMS01 to communicate with IoT Server =
118
119 == 2.1  How it works ==
120
121 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.
122
123 The diagram below shows the working flow in default firmware of NLMS01:
124
125 [[image:image-20220907171221-5.png]]
126
127 == 2.2 ​ Configure the NLMS01 ==
128
129 === 2.2.1 Test Requirement ===
130
131 To use NLMS01 in your city, 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 NLMS01 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 NLMS01 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

502 === 2.12.3  ​Battery Note ===
503
504 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.
505
506 === 2.12.4  Replace the battery ===
507
508 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).
