SE01-LB -- LoRaWAN Soil Moisture & EC Sensor User Manual

The Dragino SE01-LB 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.

23

24

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.

25

26

The LoRa wireless technology used in SE01-LB 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.

27

28

SE01-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.

29

30

SE01-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.

31

32

Each SE01-LB 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.

181

182

183

The SE01-LB 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. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

== 2.6 Datalog Feature ==

501

502

503

Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, SE01-LB will store the reading for future retrieving purposes.

504

505

506

=== 2.6.1 Ways to get datalog via LoRaWAN ===

507

508

509

Set PNACKMD=1, SE01-LB will wait for ACK for every uplink, when there is no LoRaWAN network,SE01-LB will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.

510

511

* (((

512

a) SE01-LB will do an ACK check for data records sending to make sure every data arrive server.

513

)))

514

* (((

515

b) SE01-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but SE01-LB won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if SE01-LB gets a ACK, SE01-LB will consider there is a network connection and resend all NONE-ACK messages.

516

)))

517

518

Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

522

523

=== 2.6.2 Unix TimeStamp ===

524

525

526

SE01-LB uses Unix TimeStamp format based on

527

528

535

536

537

So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25

538

539

540

=== 2.6.3 Set Device Time ===

541

542

543

User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.

544

545

Once SE01-LB 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. If SE01-LB fails to get the time from the server, SE01-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).

546

547

(% 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.**

== 6.2 Can I calibrate SE01-LB to different soil types? ==

SE01-LB 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]].
