Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. It is sensible to flammable gas: Alcohol, and Methane etc. The voltage that the sensor outputs change according to
the smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the relationship between voltage and gas concentration is as following:

• The greater the gas concentration, the greater the output voltage
• The lower the gas concentration, the lower the output voltage

In this DIY Lesson, we’ll learn how to monitor the smoke detector from remote browser

• Arduino UNO board x 1
• OSOYOO ESP8266 Wi-Fi Shield x 1
• Gas sensor module x 1
• USB cable x 1
• Jumper wires several
• 
  First, please insert the ESP8266 Wi-Fi Shield into your UNO board,
  Make sure the jumper cap is connected from E_TX to D4 and E_RX to D5.
  Connect the gas detector sensor with the mainboard as shown in the following diagram:

  A0	AO
  GND	GND
  5V	VCC

  

  Software Installation:
  Step A) Install the latest IDE from https://www.arduino.cc/en/Main/Software?setlang=en. If you have an IDE version after 1.1.16, please skip this step.

  Step B) Connect the OSOYOO Basic board to the computer via a USB cable.

  Step C) Open the IDE and choose the corresponding board type and port type for your project.

  • Board:”Arduino/Genuino UNO”
  • Port: Choose your own Serial Port for your mainboard

  Step D) Download the sketch file from https://osoyoo.com/driver/wifi-iot/lesson8/wifi-lesson8.zip,

• unzip the file, and double-click the wifi-lesson8.ino file.
• Find the following lines:

  char ssid[] = "******"; // your network SSID (name)
  char pass[] = "******"; // your network password

  Please replace the ****** with your correct wifi SSID and password; otherwise, 
  your project cannot connect to the Internet.
  

  Step E) After changing the above lines, load the sketch into the IDE.
  

  

  
  
  
  STEP A) Open your Serial Monitor. You can see that your router will assign an IP 
  address to your IDE as follows:
  
  

  In the above example, 192.168.1.81 is the IP address of my IDE, and we need to set this IP address in our app in the next step.

Step B) Open your OSOYOO IOT UDP Robot app. If you haven’t installed this app, please read the APP               installation section in Lesson 2.

      Step C) Make sure your cell phone is on the same local network as Arduino. Open the app, click       Settings, enter your Arduino IP address from Step A, and port to 8888 in settings.

Now, press any key on your app, and your screen will display something like the following picture.
