23 == 1.1 What is LoRaWAN Soil Moisture & EC Sensor ==
24
25
26 The Dragino SE01-LB/LS is a (% style="color:blue" %)**LoRaWAN Soil Moisture & EC Sensor**(%%) for IoT of Agriculture. It is designed to measure the (% style="color:blue" %)**soil moisture of saline-alkali soil and loamy soil**(%%). The soil sensor uses (% style="color:blue" %)**FDR method**(%%) to calculate the soil moisture with the compensation from soil temperature and conductivity. It also has been calibrated in factory for Mineral soil type.
27
28 It detects (% style="color:blue" %)**Soil Moisture**(%%), (% style="color:blue" %)**Soil Temperature**(%%) and (% style="color:blue" %)**Soil Conductivity**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
29
30 The LoRa wireless technology used in SE01-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
31
32 SE01-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
33
34 SE01-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%) or (% style="color:blue" %)**solar powered + li-on battery**(%%) it is designed for long term use up to 5 years.
35
36 Each SE01-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

187 == 2.1 How it works ==
188
189
190 The SE01-LB/LS is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the SE01-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

197 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.

544 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
545
546 Once SE01-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to SE01-LB/LS. If SE01-LB fails to get the time from the server, SE01-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
547
548 (% style="color:red" %)**Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**

870 == 6.2 ​Can I calibrate SE01-LB/LS to different soil types? ==
871
872 SE01-LB can be used to measure EC/Moisture in different type of soil event concrete.
873
874 (((
875 SE01-LB/LS 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/downloads/LoRa_End_Node/LSE01/Calibrate_to_other_Soil_20230522.pdf]].
