Key Features:

✔ Wide Measurement Range – 0-14 pH with ±0.1pH accuracy (depends on probe quality). ✔ Analog Output – Directly readable by microcontrollers (0-5V or 0-3.3V). ✔ Onboard Signal Conditioning – Amplifies and stabilizes the probe’s weak signal. ✔ Adjustable Gain Potentiometer – Calibrate for different pH buffers (e.g., 4.0, 7.0, 10.0). ✔ Low Power Consumption – 5V DC input (compatible with Arduino’s 5V pin). ✔ Compact & Lightweight – Easy to integrate into DIY projects.

⚠ Important Notes:

• BNC pH Electrode Probe NOT Included – Must be purchased separately.

• Calibration Required – Use standard pH buffer solutions for accuracy.

• Not Waterproof – Keep electronics dry; only the probe should contact liquids.

Applications:

• Hydroponic nutrient monitoring

• Aquarium/pond water testing

• Industrial wastewater analysis

• School chemistry experiments

• Homebrewing/fermentation control

Package Includes:

• 1 × PH Sensor Module (without probe)

• 1 × Instruction manual (calibration guide)
