Product Description:
This analog pH sensor module is perfect for building your own pH meter or creating a water quality monitoring system for tanks, aquaponics, or fish tanks. It’s an excellent tool for science experiments, water control projects, or any application requiring precise pH measurements.
What is pH?
pH measures the hydrogen ion concentration in a solution, ranging from 1 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline. This sensor helps you accurately determine the pH level of liquids for various applications.
Important Notes:
•Upon receiving the probe, you may notice white particles (KCl crystallization) on the protective foam. This is normal and occurs due to minor leakage during shipping.
•The KCl solution is removed from the cap due to shipping restrictions. Once received, store the probe in a KCl solution to maintain its functionality. Never leave it dry.

Usage Instructions:
•PO Pin:Analog output pin (0-5V only).
•VIN:5V power supply (not compatible with 3.3V devices).
•Calibration:Use the blue potentiometer near the BNC connector to adjust pH values. Short the BNC with a wire during calibration.
•Recommended Calibration:Set to 2.5V for pH 7.0 (0V = pH 0, 2.5V = pH 7, 5V = pH 14). Calibration may have a 10% tolerance.
•Connection:Connect the PO pin to an Arduino analog input pin.
•Testing:Use Arduino code to read 5V analog input (do not use with 3.3V devices).
Important Warnings:
•Avoid switching directly from alkaline to acidic solutions, as this may damage the sensor.
•Each reading takes 10 seconds to 1 minute for accurate results.
Package Includes:
1 x Analog pH Sensor/Meter Kit for Arduino (probe + board + KCl solution)Note: Buffer solutions are not included.
