Outline

  • Project: Open Source WIFI Weather Station System.(ESP8266 connected to Blynk)
  • Objective: To get temperature, humidity, light intensity and PM2.5 at the weather station.
    • Note: PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers
  • Difficulty: Medium
  • Time-consuming: 2-Hour
  • Maker: Ray

Introduction:

  • Read temperature, humidity, light intensity and PM2.5 data and display those data on the screen.
  • Upload the data to Blynk.
  • View data on phone anywhere using the Blynk app.
  • Created by Microduino with Microduino components.

Principle of the Experiment

This Weather Station can detect data including:


Other functions:

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.
Wws qr code.png


  • Once the project has loaded, click on Project Settings (nut icon).
Wws project settings.png


  • 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.

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:

Windows
MicroduinoGettingStart-ForWindows.jpg
IDE Install Guide for Windows
MAC
MicroduinoGettingStart-ForMAC.jpg
IDE Install Guide for MAC

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
  • 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

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.

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.
  • 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.

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.
