This project introduces a cost-effective and efficient solution for measuring internal air pressure within sealed containers using the HX710B digital pressure sensor paired with an Arduino microcontroller. The system is tailored to monitor pressure buildup in everyday plastic bottles, with applications in chemical reaction analysis, beverage carbonation monitoring, and safety testing.

The HX710B sensor detects pressure variations and sends high-resolution digital signals to the Arduino, which processes and displays the data in Pascals via the Serial Monitor—serving as a simple Data Acquisition System (DAS). This enables real-time pressure tracking during dynamic conditions such as shaking or heating.

The setup emphasizes accessibility, requiring minimal components and offering a practical, scalable tool suitable for educational, research, and light industrial applications. It showcases innovation by leveraging commonly available electronics to solve real-world pressure monitoring challenges.

Monitoring internal pressure in containers is critical across industries, yet traditional equipment is often expensive, bulky, or impractical for small-scale or educational environments. This project addresses the gap by offering a low-cost, compact, and accurate alternative.

Potential uses include:

• Experiments involving sealed containers and gas evolution.
• Monitoring carbonation levels in beverages.
• Safety checks in systems prone to overpressure.

Applications

• Centralized monitoring of gas cylinders to detect overpressure events in real-time.
• Educational experiments illustrating gas laws and chemical pressure dynamics.
• Food and beverage industry for carbonation and fermentation monitoring.
• Environmental research involving sealed chambers and atmospheric changes.
• Consumer packaging safety assurance through internal pressure testing.

Methodology

• The HX710B sensor detects pressure changes within a sealed test bottle and converts them into digital signals.
• The Arduino reads these signals and transmits the data to a simple DAS (Serial Monitor) for real-time visualization.

Innovation

The system replaces traditional analog setups with a digital, noise-resistant HX710B sensor—enhancing precision while reducing complexity. By integrating with an Arduino, this design eliminates the need for expensive commercial data loggers, offering an open, modular, and user-friendly alternative that can be expanded into networked systems or embedded applications.

Benefits

• Affordable and easy-to-source components.
• Portable, scalable, and suitable for various testing environments.
• Enables live data logging and analysis.
• Highly adaptable for custom applications or future IoT integration.
