Water quality monitoring system in this tutorial you will learn how to make an iot based water quality monitoring system using arduino ph sensor nodemcu esp8266 wifi module and blynk application.
Arduino water ph meter.
As this is an iot internet of things based project the water quality can be monitored from anywhere around the world.
In this project we are going to make an arduino ph meter and learn how to measure the ph of a liquid solution using a gravity ph sensor and arduino.
Looking for a low cost ph meter.
Analog ph sensor meter kit specially designed for arduino controllers and has convenient and practical gravity connector and a bunch of features instant connection to your probe an your arduino to get ph measurements at 0 1ph 25.
A 16x2 lcd is used to show the ph value on the screen.
In this project we will be making a benchtop ph meter using the gravity analog ph circuit and probe from atlas scientific and an arduino uno.
What is ph.
Most plant require acidic ph in order to breakdown the mineral for proper growth with the help of this meter one can measure the ph of water and can select appropriate water.
Applications of arduino ph meter.
Or one that you can use easily with your arduino and the raspberry pi.
With this low cost grove ph sensor kit you can easily connect a ph meter and start measuring ph in your water.
Readings will be displayed on a liquid crystal display lcd note this meter was developed on a windows.
Automation of aquaponic hydroponic or even aquarium.
Arduino ph sensor in this tutorial you will learn how to use the ph sensor with arduino and how to find the ph value of different liquids water milk and cold rink and display the ph value on the serial monitor as this is a getting started tutorial so in this tutorial we will only cover the extreme basics like for example.
Kensizer soil tester 3 in 1 soil moisture light ph meter gardening tool kit for plants care digital plant thermometer water meter for indoor outdoor no battery required 4 3 out of 5 stars 947 13 99 13.
For most hobbyist this great accuracy range and it s low cost makes this a great tool for biorobotics and other projects.
So let s get started.
By measuring the hydrogen ion activity in water based solutions this sensor gets a ph reading.
We will also learn how to calibrate the ph sensor to determine the accuracy of the sensor.
