The pH of a solution can be determined using a pH meter or a pH indicator solution. The module utilises Hydrogen-ion activity also known as the “proton activity” for measuring pH of the liquid. This ...

Here we are interfacing pH sensor and Arduino to make pH meter which can measure the pH values of any liquids and display the pH values on LCD display. You can also learn how to calibrate the Ph ...

BMP180-PressureMeasurement: Demonstrates how to measure pressure, altitude, and temperature using the BMP180 sensor module with Arduino. HCSR04-DistanceMeasurement: Demonstrates how to measure ...

This paper presents an Arduino-based monitoring system that measures four physicochemical parameters of water: pH, temperature, turbidity, and electrical conductivity to identify possible water ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...
