Description
pH Sensor Module Kit
The pH Sensor Module Kit is an analog water quality sensor designed to measure the acidity or alkalinity of liquids with high accuracy. It consists of a glass pH electrode, signal conditioning board, and BNC connector, making it easy to interface with microcontrollers such as Arduino, ESP32, Raspberry Pi and STM32.
The module measures pH values from 0 to 14 and provides an analog output that can be read using an ADC. An onboard potentiometer allows calibration to improve measurement accuracy. The sensor is widely used in hydroponics, aquaculture, water treatment plants, laboratories, environmental monitoring and IoT-based smart farming systems. Proper calibration with standard buffer solutions (typically pH 4.00, 7.00 and 10.00) is recommended for the best results.

Frequently Asked Questions (FAQs)
Is this sensor compatible with Arduino?
Yes. It works with Arduino Uno, Nano, Mega and other Arduino-compatible boards.
Can I use it with ESP32?
Yes. It is compatible with ESP32. Since ESP32 uses 3.3V ADC inputs, ensure the analog output voltage is suitable or condition the signal if required.
What pH range can it measure?
The module measures pH values from 0 to 14.
Does it require calibration?
Yes. Calibration using standard pH buffer solutions is recommended before taking measurements.
Can it measure drinking water quality?
Yes. It measures the pH of water, but it does not measure TDS, EC or dissolved contaminants. For complete water analysis, combine it with TDS, EC or dissolved oxygen sensors.
