pH Sensor Module 0-14 Range

This pH sensor module features a wide detection range of pH 0 to pH 14, designed for precise water quality monitoring and DIY electronics projects. It includes a dedicated pH electrode probe and outputs analog voltage signals: approximately 2.51 V at pH 7 (neutral) and 3.03 V at pH 4 (acidic), delivering a measurable voltage difference of -0.52 V across that segment — enabling straightforward calibration and linear interpretation. The module is built with a durable plastic and metal construction, housed in protective casing for long-term stability and safe handling. Its compact size and low-maintenance design make it ideal for repeated use in laboratories, home aquariums, hydroponic gardening, and educational circuit testing. Extensive community-supported documentation and verified code examples are available for common microcontrollers including Arduino and Raspberry Pi.
