Description

The Grove PH Sensor Kit is designed for accurate measurement of hydrogen-ion activity in aqueous solutions, determining acidity or alkalinity on the 0-14 pH scale. Its core is a glass electrode probe connected via a BNC interface to a signal conditioning driver board. This board translates the high-impedance electrode signal into a readable analog voltage for microcontrollers.

The system is engineered for durability in lab and field environments, with an operating temperature range of 0-60°C. The driver board supports both 3.3V and 5V logic, ensuring seamless compatibility with popular development platforms. Proper calibration with standard buffer solutions is required for precise measurements, and the kit includes saturated sodium chloride solution for electrode maintenance.

Key Features

  • Wide-range pH measurement from 0 (acidic) to 14 (alkaline).
  • High-input impedance driver board (≤250 MΩ) for accurate signal acquisition.
  • Standard BNC connector allows for probe replacement or upgrade.
  • Grove system connector enables plug-and-play wiring with Seeed Studio Studio and compatible platforms.
  • Designed for stable operation across a 0-60°C temperature range.
  • Includes essential calibration and electrode storage solution for long-term reliability.
  • Optimized performance-to-cost ratio for educational, research, and prototyping applications.

Applications

  • Aquaponics and hydroponics system nutrient solution monitoring.
  • Laboratory water quality analysis and educational science experiments.
  • Wastewater treatment process control and effluent pH checking.
  • Aquarium and aquaculture tank water condition monitoring.
  • Chemical process monitoring in small-scale industrial or research settings.

Frequently Asked Questions

What is the operating voltage range for this Grove pH sensor?

The driver board for the Grove pH sensor is designed to operate from a 3.3V to 5V DC power supply. This wide range ensures direct compatibility with common microcontroller platforms like Arduino (5V) and Raspberry Pi or ESP32 (3.3V) without requiring a level shifter.

How do I calibrate the pH sensor for accurate readings?

The pH electrode must be calibrated using standard buffer solutions with known pH values (e.g., pH 4.01, 7.00, 10.01) before taking measurements. For best accuracy, use a buffer solution close to the expected sample pH. The kit includes sodium chloride solution for electrode storage, but calibration buffers are typically purchased separately.

Can I replace the pH probe if it gets damaged?

Yes, the sensor features a standard BNC connector interface, allowing you to disconnect and replace the glass electrode probe with any compatible BNC-type pH electrode. This extends the life of your setup, as the driver board is reusable.

How do I connect this sensor to an Arduino or Raspberry Pi?

Connection is simplified via the Grove ecosystem. Use the included Grove cable to connect the driver board's output to an Analog port on a Grove base shield attached to your Arduino or to a compatible analog Grove port on a Raspberry Pi HAT. The board outputs an analog voltage proportional to the pH value.
