This analog pH sensor module translates the electrode’s millivolt output into a stable 0-5V analog signal compatible with standard microcontroller ADCs. The integrated signal conditioning circuit ensures reliable readings for aqueous solutions within a 0-60°C operating range. The module is designed for straightforward integration into water quality monitoring systems, aquaponics, and educational projects.
Its robust BNC connection provides a secure interface for standard glass-body pH electrodes, while the on-board potentiometer allows for precise calibration against known buffer solutions. The module operates on a single 5V DC supply, making it compatible with Arduino Uno, Mega, and other 5V logic development boards without requiring additional level shifting.
