View source for Open Source WiFi Weather Station System

==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.

|'''Note:''' Different revisions will contain different components.
Most noteable are:
*Duo-V will be replaced with a Microduino-Cube-S1.
*Humidity/TempSensor will be replaced with a Tem&Hum-S2.
|}

==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. 
::[[File:wws_qr_scan.png|300px]]


*Scan the QR code below.
::[[File:Wws_qr_code.png|300px]]


*Once the project has loaded, click on '''Project Settings''' (nut icon). 
::[[File:wws_project_settings.png|300px]]


*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.
::[[File:wws_auth_token.png|300px]]


*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:
{{Clickable software guide boxes}}
{{Clickable_headed_image_table_box_clear}}

===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 the code for Weather Station here: '''[[File:ESP8266BlynkWeatherStationV2.zip]]'''
*NON-WIFI Option: If you are having issues with WiFi or prefer a non-WiFi option use this code: '''[[File:ESP8266BlynkWeatherStationV2.zip]]'''
*Unzip the file. Under the software (Arduino IDE), go to '''File > Open...''' and navigate to the unzipped folder and open the '''ESP8266BlynkWeatherStationV2.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.

*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.  
[[File:Waetherstep5.jpg||600px]]

===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.
