pH Sensor Analog Meter Kit For Arduino

pH Sensor Analog Meter Kit for Arduino, featuring an industrial-grade glass pH electrode probe with a BNC connector, a signal conversion circuit board with operational amplifiers and gain-adjustment potentiometers, a storage bottle for reference solution, and mounting hardware accessories. This complete kit provides an accurate tool for monitoring aqueous acidity and alkalinity levels in DIY automation and water quality projects.

Features

• Equipped with a detachable glass pH electrode probe featuring a standard BNC coaxial connector
• Signal conversion board powered by operational amplifiers ensuring stable 0V to 5V analog voltage scaling
• Wide measurement range covering the full chemical spectrum from 0.0 to 14.0 pH
• High measurement accuracy of ±0.1 pH at 25°C for reliable scientific and environmental data logging
• Onboard gain and threshold adjustment potentiometers for manual calibration against standard buffer solutions
• Active LED power indicator providing visual status feedback during operation
• Standard 3-pin analog sensor interface compatible with Arduino, ESP32, and Raspberry Pi ADC inputs
• Includes complete mounting hardware for secure physical installation in control panels or enclosures

Applications

• Hydroponic nutrient solution monitoring and automated pH adjustment dosing systems
• Freshwater and saltwater aquarium water quality tracking
• Environmental water testing stations, wastewater treatment monitoring, and ecological studies
• Agricultural soil slurry testing and school science laboratory chemistry kits
• Polytechnic diploma, university engineering thesis, and Arduino/ESP32 IoT water quality projects

Important Notes:

• Glass Bulb Vulnerability: The tip of the pH probe is made of thin, sensitive glass. Handle with extreme care to avoid scratching or breaking the bulb. Do not touch the glass bulb with hard objects or fingers.
• Storage Solution Maintenance: The pH probe must be stored in a moist environment inside its protective cap using a standard storage solution. Never let the glass bulb dry out for extended periods, as this permanently ruins the electrode's response characteristics.
• Calibration Requirement: For accurate readings, calibrate the sensor module using standard pH buffer packets before deployment. Adjust the onboard potentiometers during calibration according to your project code requirements.
• Board Waterproofing: The BNC connector and the signal conversion circuit board must be kept completely dry. Only submerge the glass electrode probe tip into the liquid being tested.
