Gravity Lab Grade Analog pH Sensor Kit for Arduino/Raspberry Pi
Gravity: Lab Grade Analog pH Sensor Kit is a liquid quality monitoring solution for measuring pH from 0 to 14 with Arduino or Raspberry Pi compatible systems. It combines a laboratory-grade pH probe with a signal conversion board that accepts a wide 3.3V to 5.5V supply, making it easy to integrate into embedded projects.
The kit is designed for practical use in water testing, aquaponics, aquaculture, and other solution monitoring applications. A hardware-filtered analog output helps reduce jitter, while the Gravity interface and BNC probe connection keep wiring simple with no soldering required.
Calibration support is a major advantage here: the supported software library provides two-point calibration and can automatically identify standard buffer solutions. As supplied in the reference example, standard buffer solutions pH 4.0 and pH 7.0 are included for setup and routine recalibration.
