Gravity: Thin-film Pressure Sensor for Pressure Science Course

The Gravity: Thin-film Pressure Sensor is an educational sensing module designed for science, physics, and engineering coursework. It measures applied force by translating the deformation of a flexible film into an analog signal, making it ideal for students, educators, and makers exploring pressure measurement concepts.

Flexible film pressure detection

The sensor measures pressure through the deformation of an ultra-thin 0.4mm flexible film element. As applied force increases, the module generates a proportionally higher analog output voltage with rapid response times for real-time experiments.

Wide development board compatibility

Operating across a 3.3V to 5V range, the sensor connects seamlessly to Arduino, micro:bit, and Unihiker platforms without complex calibration. It features a standard PH2.0-3P Gravity interface for reliable plug-and-play wiring.

Comprehensive educational tutorials

Detailed step-by-step guides are provided for Arduino, micro:bit, and Unihiker platforms. These classroom-ready resources allow educators and beginners to integrate pressure experiments quickly with minimal prior experience.

Practical science and engineering applications

The module allows students to investigate load distribution, material behaviour under stress, and weight measurement in physics classes. It also supports engineering and robotics projects, such as building pressure-sensitive switches or tactile feedback systems.

Compact and lightweight form factor

Measuring 57.5 by 22mm and weighing only 2.9g, this compact module easily mounts into custom project enclosures and experimental apparatus.
