20
21
22 The WSC2-Compact-LS is Dragino's 3rd generation Weather Station Kit. It is designed for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate.
23
24 The wireless transmitter (WSC2-Compact-LS) and the sensors of the 3rd generation weather station kit are low power and no need extra power supply or MQTT. It target the provide an easy installation method and low cost to provide a Long Range Wireless weather station kit.
25
26 The Weather Station Kit includes a LoRaWAN transmitter, a 3 in 1 sensor for temperature/humidity/air pressure , Illuminance sensor and rain guage.
27
28 The 3 in 1 sensor can measure below values: Temperature, Humidity, Air pressure. The transmitter use I2C interface to communicate with the weather station. It also has a pulse count input that can be used to connect a tipping bucket Rain Gauge.

143
144 == 2.1  How it works? ==
145
146
147 Each WSC2-Compact-LS is shipped with a worldwide unique set of OTAA keys. To use WSC2-Compact-LS in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After finish installation as above. Create WSC2-Compact-LS in your LoRaWAN server and Power on WSC2-Compact-LS , it can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is 20 minutes.

152
153 This section shows an example for how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are of similar procedure.
154
155 Assume the DLOS8N is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the WSC2-Compact-LS device in TTN V3:

219
220 Uplink payloads include two types: Valid Sensor Value and other status / control command.

225 === 2.3.1 Uplink FPORT~=5, Device Status ===
226
227
228 Users can use the downlink command(0x26 01) to ask WSC2-Compact-LS to send device configure detail, include device configure status. WSC2-Compact-LS will uplink a payload via FPort=5 to server.

329 ==== Temperature ====
330
331 Example:
332
333 If payload is: 0105H:  (0105 & 8000 == 0), temp = 0105H /10 = 26.1 degree
334
335 If payload is: FF3FH :  (FF3F & 8000 == 1) , temp = (FF3FH - 65536)/10 = -19.3 degrees.
336
337 (FF3F & 8000:Judge whether the highest bit is 1, when the highest bit is 1, it is negative)

347 ==== Pressure ====
348
349 Example:

360
361 == 2.4  Unix TimeStamp ==
362
363
364 WSC2-Compact-LS uses Unix TimeStamp format based on
365
366 [[image:image-20250606172946-11.jpeg]]
367
368 Users can get this time from the link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]]
369
370 Below is the converter example
371
372 [[image:image-20250606173001-12.jpeg]]
373
374 So, we can use AT+TIMESTAMP=1742278702 or downlink 3067D9102E to set current time : March 18, 2025 06:18:22
375
376
377 == 2.5  Set Device Time ==
378
379
380 There are two ways to set the device's time:
381
382 (% style="color:blue" %)**1. Through LoRaWAN MAC Command (Default settings)**
383
384 Users need to set SYNCMOD=1 to enable sync time via the MAC command.
385
386 Once WSC2-Compact-LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and server will reply with (DeviceTimeAns) to send the current time to WSC2-Compact-LS. If WSC2-Compact-LS fails to get the time from server, WSC2-Compact-LS will use the internal time and wait for next time request (AT+SYNCTDC to set time request period, default is 10 days).
387
388 (% style="color:red" %)**Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN v3 and loriot support but TTN 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 v2 if SYNCMOD=1.**
389
390
391 (% style="color:blue" %)**2. Manually Set Time**
392
393 Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
394
395
396 == 2.6 Frequency Plans ==
397
398
399 The WSC2-Compact-LS uses OTAA mode and below frequency plans by default. Each frequency band use different firmware, user update the firmware to the corresponding band for their country.
400
401 [[http:~~/~~/wiki.dragino.com/xwiki/bin/view/Main/End%20Device%20Frequency%20Band/>>http://wiki.dragino.com/xwiki/bin/view/Main/End%20Device%20Frequency%20Band/]]

404 = 3. Configure WSC2-Compact-LS =
405
406 == 3.1 Configure Methods ==
407
408
409 WSC2-Compact-LS supports below configure method:
410
411 * AT Command via Bluetooth Connection (Recommended): [[BLE Configure Instruction>>http://wiki.dragino.com/xwiki/bin/view/Main/BLE%20Bluetooth%20Remote%20Configure/]].
412
413 * AT Command via UART Connection : See [[UART Connection>>http://wiki.dragino.com/xwiki/bin/view/Main/UART%20Access%20for%20LoRa%20ST%20v4%20base%20model/#H2.3UARTConnectionforSN50v3basemotherboard]].
414
415 * LoRaWAN Downlink.  Instruction for different platforms: See [[IoT LoRaWAN Server>>http://wiki.dragino.com/xwiki/bin/view/Main/]] section.
416
417 == 3.2 Serial Access Password ==
418
419
420 After the Bluetooth or UART connection is successful, use the Serial Access Password to enter the AT command window.
421
422 The label on the box of the node will print the initial password: AT+PIN=xxxxxx, and directly use the six-digit password to access the AT instruction window.
423
424 [[image:image-20250606173326-13.jpeg]]
425
426 If you need to change the password, use AT+PWORD=xxxxxx (6 characters)
427
428 [[image:image-20250606173341-14.jpeg]]
429
430 (% style="color:red" %)**Note: **(%%)**After entering the command, you need to add a line break, and you can also set automatic line breaks in the Bluetooth tool or UART connection tool.**
431

433
434
435 == 3.3  General Commands ==
436
437
438 These commands are to configure:
439
440 * General system settings like: uplink interval.
441 * LoRaWAN protocol & radio related command.
442
443 They are same for all Dragino Devices which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:

665 == 4.2 Solar charging instructions ==
666
667
668 Battery capacity 3000mAh, maximum charging power of solar panel: 0.9W, charging efficiency: 22
669 Normally it takes 56 hours of charging to fill the battery when the sun is right on the solar panel at midday.
670 The specific calculation process is as follows:
671
672 ~1. Battery energy capacity calculation
673 The battery voltage is 3.7v, the total energy is:
674
675 * 3000mAh × 3.7v = 11.1Wh
676
677 2. Effective charging power calculation
678 The maximum power of the solar panel is 0.9W, the charging efficiency is 22%, the actual power input to the battery is:
679
680 * 0.9W × 22% = 0.198W
681
682 3. Charging time calculation
683 Time T = total energy ÷ effective power = Total charging time
684
685 * 11.1Wh ÷ 0.198W ≈ 56.06 hours
