Gravity: Thin-film Pressure Sensor for Pressure Science Course

The Gravity Thin-film Pressure Sensor measures pressure by detecting deformation in a flexible film material. When pressure is applied, the film flexes, generating higher analog output values. Conversely, light pressure results in lower output. This sensor is an excellent tool for exploring pressure measurement concepts hands-on. With a detection range from 20g to 6kg, it provides an accessible way to understand pressure sensing technology, commonly used in educational settings and DIY projects. It easily interfaces with Arduino and micro:bit controllers.

Featuring a simple, plug-and-play design, this thin-film pressure sensor requires no complex setup or calibration, making it perfect for beginners. Its operating voltage range of 3.3V to 5V enables seamless connections to Arduino, micro:bit, and Unihiker. The straightforward analog output ensures easy integration into various projects, facilitating a smooth setup process without hassle.

The Gravity Thin-film Pressure Sensor detects a wide lateral pressure range, from 20g to 6kg, making it apt for numerous experiments. At just 0.4mm thick, the sensor element provides quick response times, allowing immediate detection and measurement of applied pressure. This is particularly advantageous in real-time experiments and demonstrations, offering compelling insights into force and pressure.

Comprehensive tutorials accompany this sensor, providing detailed guidance for integrating it with popular development boards. The step-by-step tutorials for micro:bit, Arduino, and Unihiker platforms simplify classroom projects. They help educators and students start experimenting quickly, even with limited prior knowledge, enhancing the educational experience.

This sensor significantly benefits STEM learning, especially in science and engineering courses. It allows educators to demonstrate pressure sensor principles visually, making abstract concepts more tangible. It can be utilized in physics experiments to measure weight, demonstrate load distribution, or explore material behavior under pressure. In engineering, students can incorporate it into systems like robotic arms or pressure-sensitive switches, reinforcing theoretical knowledge through practical application.
