In this picture show us that how to create our own channel in this and upload our project in this.

Feel this Details:/h3>

Channels store all the data that a ThingSpeak application collects. Each channel includes eight fields that can hold any type of data, plus three fields for location data and one for status data. Once you collect data in a channel, you can use ThingSpeak apps to analyze and visualize it.

API Keys

API keys enable you to write data to a channel or read data from a private channel. API keys are auto-generated when you create a new channel.

Copy key

In this part you saw that when you create your channel you get your different key. so copy that key and pate it into the new tab and then you see the result.

Output

When Api key is enable then after you see this output .

Key in code

In this Image we saw that while we create a channel that we get diffrent ID so copy this Id and put that id into your nodemcu + flowmeteer code. so u=you get the result.

Final Output

In this Image it is a final output of our channel and project. it show us the flow of my wtaer meter graph.

Final Result

In this picture show us that when we create a channel and then we see this type of output.

What is Nodemcu

NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module.

·code of nodemcu

Here is the code of basic nodemcu blink.

·   Steps

Step 1: What's Needed?

• The hardware connection is done by attaching 3 cables (jumper cables) between the flowmeter and the nodemcu, in order to get the on/off pulse generated by the flow of water and thus count for the litres





• Cable connections (use the breadboard cables, male-to-male)





· Connect the red cable output from the flowmeter to the 3.3v pin on the nodemcu.

· Connect the black cable output from the flowmeter to "ground" on the nodemcu.

· Connect the yellow cable output from the flowmeter to the control pin on the nodemcu (in my case the D2 pin).

Before any code, you may need to flash new firmware into the NodeMcu, use ESP8266Flasher
(https://github.com/nodemcu/nodemcu-flasher).

Step 2: Upload the code in Arduino

here is the code of nodemcu + flowmeter.

Step 3: put this in ThingSpeak

In this part you create a channel and then when you create a channel then after follow the above thingspeak steps and then you see this type of output.

Step 4: Data Fetch in Your Github page

here is the final output of my project.

Step 5: Circuit

In this pic connect Flowmeter with Arduino and i Display it with use of Lcd Diplay. conect them and code put in arduoino software and upload the code then you get the final output.
