The pH Sensor Analog Meter Converter Board for Arduino is designed to measure the pH level of liquids accurately and efficiently. This module converts the analog signal from a pH electrode (not included) into a readable output suitable for Arduino and other microcontrollers. Because pH indicates the concentration of hydrogen ions in a solution, it plays a critical role in water quality monitoring, aquaculture, hydroponics, and laboratory research. The sensor supports a full detection range from pH 0 to 14 and operates within a temperature range of 0–60°C. However, proper calibration is required before use to ensure accurate readings. With fast response time and stable performance, this converter board provides a reliable solution for embedded liquid analysis systems. Featured By RoboticsBD.
