User Manual

Compared to the standard version, the Lark Weather Station Pro includes an additional expansion module at the base. When connected, this module provides power supply, battery monitoring, GNSS positioning, and WiFi wireless data transmission functionalities.

First-Time Use

When using for the first time, you need to connect the battery manually.

  • 1.Connect the lithium battery to the expansion module using the power cable.

  • 2.Arrange the battery wiring neatly, then secure the back cover of the expansion module using four small screws.

Offline Deployment

If Wi-Fi remote data transmission is not required, you can use the offline mode directly.

  • Take the Lark Weather Station Pro to an open outdoor location and press the power button at the bottom of the expansion module. The station will automatically record data such as temperature, humidity, air pressure, wind speed, wind direction, longitude, latitude, altitude, remaining battery level, and battery voltage into an internal CSV file.

  • If the Lark Weather Station Pro is powered on indoors, it will not be able to receive satellite signals. In this case, the stored data will lack longitude, latitude, and altitude information, but all other functions will remain unaffected.

  • For instructions on how to configure the sampling frequency and other settings for the Lark Weather Station, refer to this tutorial: Lark Weather Station Function Description.

    Note: When connecting the Lark Weather Station Pro to a computer for configuration or data export, make sure to turn off the power at the bottom of the expansion module. Failing to do so may result in configuration failures or data loss.

  • After data collection is complete, first turn off the power at the bottom of the expansion compartment. Connect the computer to the Type-C interface of the weather station, and a USB drive will pop up on the computer.

  • Open the USB drive, locate the latest CSV file, and open it to view the recorded data.

Online Deployment - SIOTV1

SIOTV1 Server Configuration

  • 3.On your computer, press "Win + R" to open the cmd command line terminal.
  • 4.Type the command ipconfig and press Enter. Locate and record the IPv4 Address of the wireless LAN adapter.

The Lark Weather Station Pro and the computer must be connected to the same network

  • 5.Record the following parameters from the Siot v1 platform to configure
    • WiFi SSID: Connect to the same WiFi network as the computer running SIoT.exe. This can be a local area network.
    • WiFi Password: The password for the WiFi network.
    • MQTT Server: The IP address obtained in Step 4 (e.g., 192.168.9.187).
    • MQTT Username: siot (fixed parameter in the Siot v1 platform).
    • MQTT Password: dfrobot (fixed parameter in the Siot v1 platform).
  • 6.In your browser, enter the IP address obtained in Step 4 followed by :8080. For example: 192.168.9.187:8080.
  • 7.Click "View Device List" → "View Messages" to see the uploaded sensor data.

Lark Weather Station Pro Config

  • 1.Connect the Lark Weather Station Pro to your computer and open the "DTU_config.txt" file in the pop-up USB drive.
    (Note: When connecting the Lark Pro to a computer for configuration or data export, ensure that the power at the bottom of the expansion module is turned off. Otherwise, configuration failures or data loss may occur.)
  • 2.Replace the original content in the "DTU_config.txt" file entirely with the following content:
#=====================
DTU_Switch:on
Method:wifi
 
#=====================
WiFi_SSID:your_wifi_ssid
WiFi_PASSWORD:your_wifi_passwprd

  • Replace the WiFi_SSID, WiFi_PASSWORD, and Server_IP parameters with the data obtained from the "SIOTV1 Server Configuration."

    Ensure that no extra spaces or line breaks are added during the setup, as this may cause errors. If an error occurs, you can format the USB drive of the Lark Weather Station Pro, then power it on twice. A new configuration file will be automatically generated.

Deployment and Use

  • Disconnect the Lark Weather Station Pro from the computer and turn on the power switch at the bottom of the station.

  • Pay attention to the status of the indicator light. When the purple light starts blinking according to the sampling frequency, it indicates a successful network connection (default: every 30 seconds):

    • Yellow light stays on briefly and then turns off: System initialization

    • Green light flashes: Data is being stored in the CSV file

    • Purple light flashes: Data is being reported

    • Yellow light stays on for 3 seconds: Wi-Fi connection failed within 30 seconds. If this occurs during the first boot, Wi-Fi will be abandoned, and the device will begin normal offline operation.

    • Yellow light flashes for 10 seconds: MQTT connection failed within 60 seconds. If this occurs during the first boot, MQTT will be abandoned, and the device will begin normal offline operation.

    • You can view the data in "Step 7" of the "SIOTV1 Server Configuration."

Online Deployment - SIOTV2

You can choose to run SIOTV2 on Unihiker M10 or PC.

To obtain the IP address

Use Unihiker M10

Use the Unihiker M10 to run the Siot v2 service

The Lark Weather Station and Unihiker M10 must be connected to the same network, or connect the Lark Weather Station to the M10’s wifi hotspot.

  1. Connect the Unihiker M10 to your computer using a Type-C cable.
  2. Power on the Unihiker, then open a browser and enter 10.1.2.3 to access the webpage.
  3. In the "Network Settings" section, connect the M10 to WiFi and record the IP address displayed (e.g., 192.168.123.1).
  4. Enable the SIOT service in the “Application Switch”, and then “Open Page”.
