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 ...

PH Limit: This potentiometer is to sets a limit value of the pH sensor circuit that causes the red LED to light up and the Do pin signal to turn ON. Connect Po to Analog input A0 on Arduino, and G to ...

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 ...

These values are then shown on an LCD managed by the Arduino board. Calibration and verification of the device’s accuracy were conducted using buffer solutions with known pH values. Results: The ...

In this article, we discussed how the DHT11 Temperature and humidity sensor works and how we can use it with Arduino.

Rain Drop Sensor acts as a switch when raindrops fall to the sensor, other than that with slight tweaks in the code it can also measure the intensity of the rainfall. We Interfaced the Rain sensor ...

ISFETs allow the continuous and precise measurement of pH values by determining the concentration of certain ions in water or other aqueous media in real-time. Following the outstanding development of ...
