Product Description
The Seeed Studio Grove pH Sensor Kit is designed for measuring the acidity or alkalinity (pH) of water and other liquid solutions. It uses a high-quality pH probe connected via the Grove interface for easy plug-and-play integration with compatible base shields or adapters. The module provides an analog voltage output that corresponds to the pH value of the solution being tested, allowing microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi (via ADC) to process and convert readings into precise pH values.
This sensor kit is typically used in IoT water quality systems, aquarium monitoring, hydroponics, educational science experiments, and research setups where pH stability is important. With proper calibration using buffer solutions, it delivers accurate results over the typical pH range.
