Gravity: Thin-film Pressure Sensor for Pressure Science Course

The Gravity: Thin-film Pressure Sensor measures pressure through the deformation of a flexible film material. As pressure increases, the film deforms, producing higher analog output values, while lighter pressure results in lower output. This sensor is an excellent educational tool for hands-on exploration of pressure measurement concepts. The detection range is from 20g to 6kg. It is widely used in school science and engineering courses, as well as in DIY projects, providing students and educators with an accessible way to understand and demonstrate pressure sensing technology. The sensor can be easily connected to Arduino and micro:bit controllers.

Simple, Plug-and-Play Design

Designed for ease of use, the thin-film pressure sensor requires no complex setup or calibration, making it ideal for beginners. With an operating voltage range of 3.3V to 5V, it can be seamlessly connected to Arduino, micro:bit, and Unihiker. Its analog output makes it straightforward to integrate into various projects, ensuring a smooth setup process.

Versatile Pressure Detection

The Gravity: Thin-film Pressure Sensor has a wide lateral pressure range, capable of detecting forces from as little as 20g to as much as 6kg, making it suitable for a variety of hands-on experiments. The thin sensor element, just 0.4mm thick, offers quick response times, allowing for immediate detection and measurement of applied pressure, which is particularly useful in real-time experiments and demonstrations.

Comprehensive Tutorials for Popular Development Boards

To support learning, the thin-film pressure sensor comes with detailed tutorials for popular development platforms commonly used in education.

These step-by-step guides simplify sensor integration into classroom projects, allowing students and educators to start experimenting quickly, even with minimal prior knowledge.

Educational Applications: Enhancing STEM Learning

This sensor is highly valuable in science and engineering courses, where students are introduced to the principles of force and pressure. It enables educators to visually demonstrate how pressure sensors work, making abstract concepts more tangible. It can be used in physics experiments to measure weight, demonstrate load distribution, or explore the behavior of different materials under pressure. 

In engineering courses, students can use the sensor to build basic systems incorporating sensor feedback, such as robotic arms or pressure-sensitive switches. This hands-on approach helps reinforce theoretical knowledge through practical experience.
