Project Description:
********************
In today’s episode, you will learn how to make an IoT based water quality monitoring system using Arduino, pH Sensor, Nodemcu esp8266 wifi module and Blynk Application. As this is an IoT “Internet of Things” based project, the water quality can be monitored from anywhere around the world. In this episode, I will practically explain how to measure the pH value of the Well water, and I will also explain whether the water under test is good or bad for health. In this Tutorial, you will also learn how to use the 16x2 LCD widget in the Blynk application. This is Version2 of the pH sensor Water Quality Monitoring System.

While in Version1 I covered the extreme basics like for example
What is pH?
How does a pH sensor work?
How to measure the pH value of different liquids?
In version1 I also explained how to calibrate the pH sensor. So if you are using a pH sensor for the First time then I highly recommend first you should watch Version1 and then you can resume from here.

In this episode, we will cover
1. Complete Circuit Diagram
2. pH sensor Unboxing
3. pH Sensor Pinout
4. pH sensor and Nodemcu ESP8266 wifi module interfacing with Arduino.
5. Arduino and Nodemcu Programming and finally
6. Testing
