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.

44.2	30	It can detect (% style="color:blue" %)Soil Moisture, Soil Temperature and Soil Conductivity(%%), and upload its value to the server wirelessly.
1.1	31
42.2	32	The wireless technology used in NSE01 allows the device to send data at a low data rate and reach ultra-long distances, providing ultra-long-distance spread spectrum Communication.
4.2	33
44.2	34	NSE01 are powered by (% style="color:blue" %)8500mAh Li-SOCI2(%%) batteries, which can be used for up to 5 years.
