Interfacing Sensors: Pressure, Force, Motion, and Humidity

Every smart device relies on its ability to perceive the physical world, from detecting a finger press to measuring atmospheric changes. Understanding how to select, wire, and program these sensors is the foundation of modern embedded systems design. This text-based course guides you from the fundamental physics of transduction to writing clean, efficient code that reads real-world data. You will gain a solid grasp of how pressure, force, motion, and humidity sensors operate, how they communicate with microcontrollers, and how to process their signals reliably. What you'll learn: - Understand the physical working principles behind pressure, force, inertial motion, and relative humidity sensors. - Configure standard serial communication protocols like I2C and SPI to retrieve digital sensor data. - Apply basic calibration techniques and digital filtering to clean up noisy sensor readings. - Implement low-power strategies, such as interrupt-driven sampling, to conserve battery life in embedded designs. - Interpret datasheet specifications to select the right sensor for your project requirements. You will start by mastering foundational sensor terminology and electrical characteristics before moving on to step-by-step code walkthroughs and practical interface strategies. This course is designed for beginners in embedded systems, electronics hobbyists, and aspiring hardware engineers with a basic understanding of programming.
