An Arduino Uno pH sensor measures the acidity or alkalinity of a solution by detecting hydrogen ion concentration. It's commonly used in hydroponics, aquariums, and environmental monitoring for pH ...

Microcontrollers Arduino UNO: A general-purpose microcontroller board used to control sensors and relays, manage input/output devices, and process automation logic. NodeMCU ESP8266: A microcontroller ...

So before starting with this smart water quality monitoring system using Arduino project, you can also check our previous projects to get a better understanding: IoT based Smart Irrigation System ...

As mentioned earlier, this circuit takes its power directly from the Arduino UNO R4 board’s 5 V and GND pins. The pH-detection module’s pin P0 was connected to the Arduino board’s analog pin A0. This ...

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. A 16x2 LCD is used to show the pH value on the ...

Abstract: This paper presents a smart irrigation system which is economical and gives the automation in the farm. The aim of this paper is to design an Arduino based controlled irrigation system using ...
