Liquid pH Value Detection Sensor Module V1.1 for Arduino (Analog pH Sensor Interface Module)

The Liquid pH Value Detection Sensor Module V1.1 is an analog pH signal conditioning module designed to interface with external pH electrodes for measuring the acidity or alkalinity of liquid solutions. The module converts the high-impedance signal from a compatible pH probe into an analog voltage that can be easily read by microcontrollers. Designed for Arduino, ESP32, STM32, and Raspberry Pi (with an external ADC), it is ideal for water quality monitoring, hydroponics, aquaculture, laboratory experiments, and environmental sensing applications.

Note: This product includes the pH sensor interface module only. pH probe/electrode is not included.
