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

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.

57.6	458	=== 2.4.9 +5V Output ===
4.2	459

57.7	461	NSE01 will enable +5V output before all sampling and disable the +5v after all sampling.
4.2	462
57.6	463
	464	The 5V output time can be controlled by AT Command.
	465
57.7	466	(% style="color:blue" %)AT+5VT=1000
57.6	467
	468	Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
