The DFRobot Gravity Analog pH Meter V2 is an upgraded sensor module designed for precise measurement of solution pH, reflecting its acidity or alkalinity. It employs a laboratory-grade glass electrode probe connected via a standard BNC interface, providing a stable analog voltage signal proportional to the pH value. The onboard voltage regulator and signal conditioning circuitry ensure a clean, low-jitter output suitable for direct ADC input on microcontrollers.
This version features improved precision and a user-friendly software library that simplifies the critical two-point calibration process. The module operates reliably across a broad temperature range of 0°C to 60°C, making it suitable for applications in aquaponics, hydroponics, aquaculture, and environmental water quality monitoring where robust and accurate pH data is essential.
