This is part two of IoT ESP8266 Series. To see part 1 refer to this instructable IoT ESP8266 Series: 1 Connect to WIFI Router.

This part aims to show you how to send your sensor data to one of the popular IoT free cloud service https://thingspeak.com. The data could be any data you would sense such: Temperature, Humidity, air pollution measurements or even GPS location .

Step 1: Set a ThingSpeak Channel

Open ThingSpeak.com

To set your ThingSpeak configuration do the following steps

  1. Sign up
  2. Make a new channel
  3. Name the channel (e.g. Weather, if you are monitoring weather data)
  4. set Fields ( e.g. Temp, if you are welling to measure temperature). You can add up-to 8 channels for every channel
  5. Remember your Channel ID
  6. Go to API Keys and remember yourWrite API Key

Step 2: Required Components and Circuit

    1. ESP8266 ESP-12E NodeMCU
    2. ts USB cable
    3. Potentiometer
    4. Breadboard and wires

    The Potentiometer‚ÄŹ output goes to A0 in the ESP8266, one side to GND and the other to 3.3 V

    Step 3: Code

    Download ThingSpeak Library and import it.

    Download my code

    Set myChannelNumber toyour Channel Number that you have already remembered.

    Set myWriteAPIKey to your Write API Key that you have already remembered.
