The pH Sensor Module is a signal conditioning board designed to interface with standard pH probes for liquid acidity and alkalinity measurement. It converts the weak signals from a pH probe into a stable analog voltage output that can be easily read by microcontrollers such as Arduino, ESP32, STM32, or Raspberry Pi. With onboard calibration and stable performance, this module is widely used in water quality monitoring, aquariums, hydroponics, and lab experiments.
Features:
- Designed to interface with pH glass electrode probes.
- Provides an analog voltage output for microcontrollers.
- Compatible with Arduino, ESP32, STM32, and Raspberry Pi.
- Onboard potentiometer for calibration and accuracy adjustment.
- Stable and reliable signal conditioning circuit.
- Suitable for aquariums, hydroponics, water treatment, and scientific projects.
