A pH meter measures the hydrogen-ion activity in water-based solutions, indicating its acidity or basicity expressed as pH. (Wikipedia: pH Meter). pH level is an important indicator in many scenarios, especially in monitoring soil conditions and water quality. A pH sensor is widely used in farming, gardening, hydroponics, aquaponics, swimming pools and spas, sewage treatment, education, environmental monitoring, and many other applications.
