pH Sensor Kit for Arduino – 5V with Amplifier Circuit

Bring pH measurement into your next Arduino project with this 5V analog pH sensor kit. Designed for Arduino controllers, it connects through a BNC probe connector and a PH2.0 sensor interface to help you read pH values through your controller’s analog input.

Key features

• Arduino-oriented design: A practical way to add pH sensing to your controller-based projects.
• 0–14 pH measuring range: Measure across the acidic, neutral and alkaline scale.
• Power indicator LED: Provides a visible indication that the module is powered.
• BNC connector and PH2.0 interface: Connect the pH probe to the module and interface with your Arduino’s analog input.
• Protective storage: Supplied in a compact plastic box with foam for storage and transport.

Technical specifications

• Input supply voltage: 5V DC
• Measuring range: 0–14 pH
• Measuring temperature: 0–50°C
• Stated accuracy: ±0.01 pH
• Connections: BNC connector and PH2.0 sensor interface
• Controller compatibility: Arduino controllers

Getting started

Connect the pH probe to the BNC connector, then connect the module’s PH2.0 interface to your Arduino controller’s analog input with the appropriate power connections. Use suitable Arduino code to read the sensor output and display the pH value.

From a workbench experiment to a controller-based sensing project, this kit gives you a compact starting point for exploring pH measurement.
