Xiaoling 32.2 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.
David Huang 25.1 18
Xiaoling 32.2 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.

David Huang 25.1 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.
Xiaoling 38.9 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.

Xiaoling 33.2 121
David Huang 25.1 122 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.
