PH Sensor with Module
৳2599
The pH Sensor with Module is a practical tool for measuring the acidity or alkalinity of solutions. Designed with a probe and signal conditioning board, this sensor provides stable readings and easy integration with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
It’s widely used in hydroponics systems, aquariums, environmental monitoring, agriculture, and chemistry labs in Bangladesh. With its plug-and-play interface, students and professionals can quickly set up water quality monitoring projects or automated pH control systems. Reliable, accurate, and affordable — a must-have sensor for DIY electronics and research projects.
pH is a measure of the acidity or alkalinity of a solution, ranging from 0 to 14 and defined by the concentration of hydrogen (H⁺) ions. A pH sensor quantifies this by measuring the potential difference between two electrodes: a reference electrode (silver/silver chloride) and a glass electrode sensitive to hydrogen ions—together forming the probe.
An accompanying signal conditioning circuit processes the probe’s output, allowing seamless integration with microcontrollers such as Arduino for accurate pH measurement in various applications.
