44.2	28	Dragino NSE01 is an (% style="color:blue" %)NB-IOT soil moisture & EC sensor(%%) for agricultural IoT. Used to measure the soil moisture of saline-alkali soil and loam. The soil sensor uses the FDR method to calculate soil moisture and compensates it with soil temperature and electrical conductivity. It has also been calibrated for mineral soil types at the factory.

23.2	438
57.8	439	Digital Interrupt refers to pin (% style="color:blue" %)GPIO_EXTI(%%), and there are different trigger methods. When there is a trigger, the NSE01 will send a packet to the server.
4.2	440
57.6	441	The command is:
4.2	442
57.8	443	(% 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]]).
4.2	444
	445
57.6	446	The lower four bits of this data field shows if this packet is generated by interrupt or not. [[Click here>>\|\|anchor="H"]] for the hardware and software set up.
4.2	447
	448
57.6	449	Example:
4.2	450
57.6	451	0x(00): Normal uplink packet.
4.2	452
57.6	453	0x(01): Interrupt Uplink Packet.

	456
57.6	457	=== 2.4.9 +5V Output ===
4.2	458
57.7	459	NSE01 will enable +5V output before all sampling and disable the +5v after all sampling.
4.2	460
57.6	461
	462	The 5V output time can be controlled by AT Command.
	463
57.7	464	(% style="color:blue" %)AT+5VT=1000
57.6	465
	466	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
