Introduction: WATER SUPPLY ALERT & MONITORING SYSTEM #Blynk
Update 6/03/2017: Email notification problem fixed.
Scan New QR code & use latest code.
First of all many thanks to Mr. Paul Alcock for writing code & helping me.

Now a days we are facing an issue that is our municipal corporation doesn’t provide
water supply at fix time. To solve this problem we have made a device which gives notification on our smartphone regarding water supply. It also gives information such as water flow rate & how much water we consume . This device can be used as water leakage system by using two water flow sensors.
We can also control any external appliances like Pump from anywhere over the internet. In this project we have used Blynk App. Blynk is application which provides us dashboard as well as connectivity. you can download it from google play store (for Android).& app store (for apple).
If you don't know how use Blynk please read this getting started tutorials
Step 1: Requirements
1) Nodemcu wifi module.
2) Liquid flow rate sensor
4) Switch Board
1) Latest Arduino IDE
2) Blynk (Application)
Step 2: App Setup
Download And install Blynk app.
create new account .
NOTE - For this project 4600 energy points are required make sure you have enough energy points.(On new account Blynk gives 2000 free energy points)
