Analog pH Sensor SEN0161V2

Reliable and cost-effective analog pH probe for measuring the hydrogen potential of liquids from 0 to 14, ideal for educational and experimental projects with Arduino.

Features
The SEN0161V2 pH sensor is an analog probe designed to measure the pH of liquid solutions over a wide range from 0 to 14, at temperatures between 0 and 60 °C. It outputs an analog voltage proportional to the pH value, making it easy to read using an analog input on an Arduino-compatible board.

This V2 version improves upon the previous model by offering a wider power supply range (3.3 to 5.5 V), made possible by an integrated voltage regulator. It is supplied with two buffer solutions (pH 4.0 and pH 7.0), enabling accurate two-point calibration.

The module can be easily connected to an analog input or to an I/O expansion shield using the included cable. A dedicated software library is available in the technical documentation to simplify integration and use.

Please note: measurements must be performed in a stationary, electrically neutral liquid. The probe must not remain permanently immersed in the solution being measured.
