Detailed Description:

Precisely measure the acidity or alkalinity of liquids with the pH Sensor Module, a comprehensive and user-friendly solution for all your water quality and chemical monitoring projects. This kit comes complete with a sensitive glass pH Electrode Probe and a robust signal conditioning board, providing everything you need to accurately determine the pH value of a liquid on a scale of 0 to 14. It is a fundamental component for applications in hydroponics, aquariums, agriculture, environmental science, and home automation systems.

The sensor works by measuring the hydrogen ion activity in a solution and generating a proportional millivolt signal. The included signal conditioning board amplifies and linearizes this small voltage, providing a clean and stable analog output (typically 0 to 5V) that can be connected directly to an analog input pin on a microcontroller like an Arduino, ESP32, or Raspberry Pi. The standard BNC connector on the board allows for quick and easy connection of the probe and future replacement if needed.

For high-precision applications, the sensor requires calibration using standard buffer solutions of known pH values (e.g., pH 4.0 and pH 7.0). This process is straightforward and involves adjusting an on-board potentiometer or calibrating the readings directly in your code to map the sensor's voltage output to accurate pH values. The module is designed to operate on a 5V DC supply and provides a responsive, low-noise output. With its reliability, wide application range, and simple interface, this pH Sensor Module is the go-to tool for hobbyists, students, and professionals in Pune, Maharashtra, India, looking to build robust and accurate liquid monitoring systems.

This pH Sensor Module allows microcontrollers to measure pH levels of a liquid, typically ranging from 0 to 14, where 7 is neutral. The module consists of a high-sensitivity pH electrode probe and an analog interface board which converts pH readings into voltage (0–5V), readable by Arduino or any ADC-enabled microcontroller.

The sensor is perfect for DIY environmental monitoring systems, automated hydroponic nutrient control, or educational science experiments. The included potentiometer allows onboard calibration of the voltage-pH output relationship.

Note: Calibrate with standard buffer solutions (pH 4.00, 7.00, 10.00) before use.
