About this item

The DFRobot Gravity Analog pH Sensor is a reliable and easy-to-use sensor designed for measuring the pH level of liquids in various applications such as environmental monitoring, hydroponics, aquariums, and water quality testing. It measures the acidity or alkalinity of a solution by outputting an analog voltage signal that corresponds to the pH value, which can be easily read by an Arduino or other microcontroller’s analog input. This sensor uses a high-precision pH electrode probe connected to a signal conditioning board, which amplifies and converts the weak signal from the probe into a stable voltage output. The sensor is compatible with standard 3.5mm BNC connectors, allowing easy replacement or upgrades of the probe. Designed to be robust and waterproof, the sensor can be immersed in liquids for continuous monitoring. It features an onboard operational amplifier to ensure accurate readings and reduce noise interference. The Gravity interface simplifies connection with Arduino and other microcontroller platforms, facilitating quick prototyping and integration. This sensor is ideal for projects where precise pH monitoring is crucial for maintaining optimal chemical or biological conditions.
