Principle of the Experiment
This Weather Station can detect data including:
- Temperature and humidity via Microduino-Temp&Hum
- Light intensity via Microduino-Light
- Air quality via Microduino-Air Quality
- PM2.5 via GP2Y1010AU0F
Other functions:
- Use the Microduino-Core+ to analyze and process sensor data.
- Display data on the Microduino-OLED.
- Connect the Weather Station with Blynk via Microduino-WIFI(ESP).
- Each sensor connects with Microduino-Sensorhub.
Get and Configure Blynk
Next, we'll learn how Microduino interacts with Blynk through the configuration process of the Weather Station.
Download the Blynk App
Visit the Google Play Store or the Apple App Store and download the Blynk app.
You'll need to setup an account with Blynk before proceeding. Please use a valid e-mail as your authentication tokens will be sent to that e-mail.
Using the Blynk App
- On the main screen of the Blynk app. Click on the QR code scanner to scan the Weather Station app.
- Scan the QR code below.
- Once the project has loaded, click on Project Settings (nut icon).
- Under Auth Tokens, click on Email all. This will send the authentication token to your registered e-mail. Make note of this, as you will need this token later.
- Click back to return to the Weather Station app.
Programming
Software Setup
Please follow the guide to ensure your software is correctly setup. The software is required to program the WiFi Weather Station.
Download the latest software for your operating system and follow the getting started guides:
Programming the Weather Station
- Stack Microduino-Core+ and Microduino-USBTTL together.
- Connect Microduino-USBTTL with a USB cable. Connect the other end to the PC being used.
- Open the Arduino IDE for Microduino development environment. (Please refer to the #Software Setup section).
- Configure the software to upload to the Core+ module as follows:
- Tools > Board > Microduino/mCookie-device
- Tools > Processor > Microduino/mCookie-Core+ (644pa)@16M,5V
- Tools > Port > select the port (On MacOS, NOT the Bluetooth one).
- Download
- Code for Weather Station here: File:WiFiWeatherStationV3.zip
- Unzip the file. Under the software (Arduino IDE), go to File > Open... and navigate to the unzipped folder and open the WiFiWeatherStationV3.ino file.
- The sketch with multiple files will open. Click on the userDef.h tab. You'll need to configure the WiFi connection (2.4GHz networks, non 5GHz) with:
- SSID
- PASS (WiFi password)
- auth key as noted earlier in the Blynk app sent to you via e-mail.
- #define ENABLE WIFI
- Uncommented: WiFi is enabled. (default)
- Comment out: WiFi is disabled. (Add to 2 slashes to comment out: //#define ENABLE WIFI)
- #define ENABLE_FAHRENHEIT
- Uncommented: Temperature is displayed in Fahrenheit units. (default)
- Comment out: Temperature is displayed in Celsius units. (Add to 2 slashes to comment out: //#define ENABLE_FAHRENHEIT)
- Click on the upload button (right arrow icon on the top left) to upload the program.
- The program will compile and upload. Once completed a upload successful message will appear on the bottom left.
Hardware Buildup
Step 1
- Fixate Microduino-OLED and Structure-A1 with screws.
Step 2
- Assemble Structure-B1~B5 with Structure-B6.
Step 3
| Note: Different revisions of this kit may contain different components. Either a Duo-H or Cube-S1 should be used. Duo-H is illustrated. |
- Fixate Microduino-Duo-h / Microduino-Cube-S1 on Structure-A2 with screws and nuts.
- Stack the following modules on Microduino-Duo-h / Microduino-Cube-S1.
- Microduino-Core+
- Microduino-USBTTL
- Microduino-WiFi
- Microduino-Sensorhub (on the very top of the stack)
- Attach the included adhesive strip onto the PM2.5 Sensor GP2Y1010AU0F, then to the base board.
Step 4
| Note: Different revisions of this kit may contain different components. Either a Temp&Hum or Tem&Hum-S2 should be used. Temp&Hum is illustrated. |
- Assemble the following sensors with Structure-B7, B8, B9.
- Temperature and humidity sensor (Microduino-Temp&Hum / Tem&Hum-S2)
- Air quality detector (Microduino-Air Quality)
- Light sensor (Microduino-Light)
Step 5
| Note: Different revisions of this kit may contain different components. Either a Temp&Hum or Tem&Hum-S2 should be used. Temp&Hum is illustrated. |
- Connect the sensors below to Microduino-Sensorhub using a connector wire.
- Temperature and humidity sensor (Microduino-Temp&Hum / Tem&Hum-S2) to a pin IIC.
- Air quality detector (Microduino-Air Quality) to pin A2/A3.
- Light sensor (Microduino-Light) to pin A0/A1.
- PM2.5 to pin 4/5.
- OLED screen to a pin IIC. (Not illustrated).
- Refer to the picture below, stack all sensors on the slot of Structure-B1 and Structure-B2.
- After that, connect Structure-A1 and Structure-A2 at the top and bottom of the system respectively.
Step 6
- Complete the steps above, plug in a USB cable then fixate Structure-B0. Congratulations! You finished the buildup of the Weather Station.
Step 7
- Power on the Weather Station.
- The Weather Station will connect to the WiFi network. This may take a minute or so.
- After connecting, the OLED screen will display the sensor data.
- If the data does not display, check the serial port in the IDE. It should display debugging information.
Step 8
- If the Weather Station successfully connect to the WiFi network. You can now view the data on the Blynk Phone app.
- WiFi Weather Station successfully connected to the WiFi network.
- Return to your phone which is running Blynk. Open the Weather Station project. Click on Start (play icon).
- The sensor data should start streaming to the Blynk app.
Notes
- Please make sure the verification code (blynk token) is configured right.
- Make sure your router runs normally, the SSID and password are correct.
- Routers that require login, such as some public open networks that require accepting terms of service before internet is provide is not supported. As the WiFi module cannot interact with web pages.
- If there is no display on the OLED (fuzzy screen) for more than 5 minutes, then the device may have issues connecting to the WiFi network. You may check the Serial port for debugging messages. Disable WiFi mode and see if the issue persists.
