32.2	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.
25.1	17
32.2	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
25.1	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.
38.9	21
	22	NLMS01 supports different uplink methods include (% style="color:blue" %)TCP,MQTT,UDP and CoAP (%%)for different application requirement.
	23
	24	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).
	25
	26	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.

26.1	112	== 2.1 How it works ==
25.1	113
33.2	114
25.1	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:

	129
	130	* Your local operator has already distributed a NB-IoT Network there.
	131	* The local NB-IoT network used the band that NLMS01 supports.
	132	* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
	133

27.1	402	=== 2.4.8 Digital Interrupt ===
25.1	403
33.3	404
33.4	405	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.
25.1	406
	407	The command is:

33.4	409	(% style="color:blue" %)AT+INTMOD=3 (%%) ~/~/ (more info about INMOD please refer [[AT Command Manual>>url:https://www.dragino.com/downloads/downloads/NB-IoT/NBSN95/DRAGINO_NBSN95-NB_AT%20Commands_v1.1.0.pdf]]).
25.1	410
	411	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.
	412
	413	Example:
	414
	415	0x(00): Normal uplink packet.
	416
	417	0x(01): Interrupt Uplink Packet.
	418
33.3	419
27.1	420	=== 2.4.9 +5V Output ===
25.1	421
33.3	422
25.1	423	NLMS01 will enable +5V output before all sampling and disable the +5v after all sampling.
	424
	425	The 5V output time can be controlled by AT Command.
	426
33.4	427	(% style="color:blue" %)AT+5VT=1000
25.1	428
	429	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.

25.1	465
33.3	466
25.1	467	The NLMS01 has an internal LED which is to show the status of different state.
	468
	469	* 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)
	470	* Then the LED will be on for 1 second means device is boot normally.
	471	* After NLMS01 join NB-IoT network. The LED will be ON for 3 seconds.
	472	* For each uplink probe, LED will be on for 500ms.
