Title of Activity

 Research pH Stamp Circuit (Sensor For Arduino)

Objective

Interface with arduino for pH sensor

Content/Procedure

    pH circuit designs that are available on the are antiquated and use a significant number of overly complex analog components. pH circuit enables the engineer to easily incorporate scientific grade pH monitoring into your embedded system using modern components and communication methods. With a wide operating voltage (2.5V to 5.5V) and a simple RS-232 communication protocol, the pH circuit is an easy to use specifically designed for modern embedded computer systems. pH circuit  is designed for both continuous and intermittent readings. After calibration, the pH probe can be immersed in a liquid and operate continuously for 12 months before recalibration is recommended.

pH Sensor For Arduino

Wiring Diagram

Wiring Connection For pH Sensor

Features

• Full range pH reading from .01 to 14.00
• Accuracy within two significant
• Single reading or continuous reading modes
• Temperature dependent or independent readings
• Simple calibration protocol
• Simple RS-232 connectivity (voltage swing 0-VCC)
• Simple instruction set consisting of only 11 commands
• Micro footprint circuitry
• Debugging LED's
• 2.5V to 5.5V operational voltage
• Low power consumption 

Result/Analysis

• Best solutions for calibration, pH probe, and even a board to connect directly to microcontroller (easy to troubleshot)
• The pH Stamp outputs data from the probe over serial, so it friendly to use.
