The Liquid pH 0–14 Value Detection Regulator Sensor Module is an essential electronic module designed to measure the acidity or alkalinity (pH level) of liquid solutions with high precision. Whether you’re working on a water quality monitoring system, hydroponics project, environmental research, or industrial automation, this module delivers accurate, reliable, and real-time pH readings compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
Understanding pH and Its Importance
The pH value of a liquid is a measure of how acidic or alkaline it is, ranging from 0 (very acidic) to 14 (very alkaline), with 7 being neutral. Monitoring pH levels is critical for applications in agriculture, aquaponics, laboratory analysis, chemical processing, and even food and beverage production.
The Liquid pH Sensor Module helps you measure these values electronically, making it a perfect fit for IoT-based water analysis systems or automated pH regulation setups.
