Arduino Water Ph Meter

Looking for a low cost ph meter.

Arduino water ph meter.

Or one that you can use easily with your arduino and the raspberry pi. 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. Automation of aquaponic hydroponic or even aquarium. 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.

So let s get started. For most hobbyist this great accuracy range and it s low cost makes this a great tool for biorobotics and other projects. What is ph. The onboard voltage regulator chip supports the wide voltage supply of 3 3 5 5v the output signal filtered by hardware has low jitter.

Most freshwater aquarium fish require ph of 6 8 to 7 6 for do best. As this is an iot internet of things based project the water quality can be monitored from anywhere around the world. By measuring the hydrogen ion activity in water based solutions this sensor gets a ph reading. 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.

A 16x2 lcd is used to show the ph value on the screen. With this low cost grove ph sensor kit you can easily connect a ph meter and start measuring ph in your water. We will also learn how to calibrate the ph sensor to determine the accuracy of the sensor. 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.

Readings will be displayed on a liquid crystal display lcd note this meter was developed on a windows. Applications of arduino ph meter. Analog ph meter v2 is specifically designed to measure the ph of the solution and reflect the acidity or alkalinity as an upgraded version of ph meter v1 the sensor greatly improves the precision and user experience.
