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	440
4.2	441
57.6	442	Digital Interrupt refers to pin GPIO_EXTI, and there are different trigger methods. When there is a trigger, the NSE01 will send a packet to the server.
4.2	443
57.6	444	The command is:
4.2	445
57.6	446	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	447
	448
57.6	449	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	450
	451
57.6	452	Example:
4.2	453
57.6	454	0x(00): Normal uplink packet.
4.2	455
57.6	456	0x(01): Interrupt Uplink Packet.

57.6	461	=== 2.4.9 +5V Output ===
4.2	462
	463
57.6	464	NSE01 will enable +5V output before all sampling and disable the +5v after all sampling.
4.2	465
57.6	466
	467	The 5V output time can be controlled by AT Command.
	468
	469	(% style="color:blue" %)AT+5VT=1000
	470
	471	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
