The pH Analog Sensor is a measurement module that reads the acidity or alkalinity of a liquid and sends an analog signal you can process with an Arduino or any compatible microcontroller. It is ideal for hobbyists, students, and growers who want to monitor water quality in hydroponics, irrigation tanks, aquariums, or DIY electronics projects without buying an expensive handheld meter.
Key features
- Analog output that connects easily to Arduino and similar microcontroller boards.
- Designed for measuring the acidity (pH) level of liquids.
- Simple to wire into beginner and advanced electronics projects.
- Compact module suited for breadboard and prototype builds.
- Reusable probe for repeated readings during a growing or testing cycle.
Typical uses
- Monitoring nutrient solution pH in hydroponic and home-garden setups.
- Checking acidity of irrigation or storage water before use.
- Aquarium and fish-tank water-quality projects.
- School, university, and maker electronics experiments.
How to choose / tips
- Confirm your board accepts an analog input pin for the sensor reading.
- Calibrate the probe with reference buffer solutions for accurate results.
- Rinse the probe with clean water between readings and store it properly.
