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.
29
30 It can detect (% style="color:blue" %)**Soil Moisture, Soil Temperature and Soil Conductivity**(%%), and upload its value to the server wirelessly.
31
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.
33
34 NSE01 are powered by (% style="color:blue" %)**8500mAh Li-SOCI2**(%%) batteries, which can be used for up to 5 years.

936 You can change the battery in the LSE01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.

940 The default battery pack of LSE01 includes a ER18505 plus super capacitor. If user can’t find this pack locally, they can find ER18505 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)

1090 How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.

1106 For example, in **US915** band, the frequency table is as below. By default, the end node will use all channels (0~~71) for OTAA Join process. After the OTAA Join, the end node will use these all channels (0~~71) to send uplink packets.

1148 == 4.2 ​Can I calibrate LSE01 to different soil types? ==
1149
1150 LSE01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at [[this link>>https://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/LSE01/&file=Calibrate_to_other_Soil_20220605.pdf]].
