PH Sensor

A pH sensor is an electronic device used to measure the acidity or alkalinity of a liquid. It determines the pH value on a scale from 0 to 14, where:

• pH < 7 → Acidic

• pH = 7 → Neutral

• pH > 7 → Alkaline (Basic)

pH sensors are widely used in water quality monitoring, agriculture, aquariums, laboratories, and industrial applications.

How It Works

The pH sensor consists of a pH probe (glass electrode) and a signal conditioning module.
When the probe is dipped into a liquid, it generates a small voltage proportional to the hydrogen ion concentration. This voltage is converted into a readable pH value by the sensor module.
