Gravity Analog pH Sensor Kit
Overview
The SEN0161 is a specialized analog pH sensor kit designed for the Gravity interface, enabling easy integration of liquid acidity measurements into embedded projects. It includes a pH probe and a signal conditioning board that converts the high-impedance output of the electrode into a linear voltage signal compatible with standard ADCs. The system supports a measurement range of 0-14 pH with an operating voltage of 5V.
Why Choose This Part
The kit simplifies complex pH measurements by integrating a BNC connector and signal conditioning circuitry on a single 43mm by 62mm board. It provides a simple analog output that maps 0-14 pH to a voltage range, and the standard Gravity PH2.0 interface eliminates the need for soldering during prototyping.
Applications
Key Specifications
Getting Started
Connect the pH probe to the BNC connector on the board and link the Gravity interface to an Arduino ADC pin using the provided cable. Calibration is required before use, involving soaking the probe in pH 7.0 and pH 4.0 buffer solutions to determine the offset and slope for your software. Ensure the board is powered at a stable 5V for accurate measurement results.
