Sensors play a crucial role in embedded systems by detecting changes in physical quantities, such as temperature, light, or pressure, and converting these changes into electrical signals that can be processed by microcontrollers. This interaction allows embedded systems to monitor and control external environments, providing input for decision-making processes . Sensors are typically interfaced with microcontrollers through analog-to-digital converters (ADC) or digital interfaces such as I2C, SPI, or UART, allowing the data collected by sensors to be processed by the embedded software within t

Key components necessary for designing an embedded system include processors, memory, and peripherals, often integrated as a System on a Chip (SoC) to reduce size, power consumption, and cost . Processors provide the computational power needed to perform tasks, while memory is used to store code and data. Peripherals allow the system to interact with external devices . Sensors and actuators are crucial for detecting physical stimuli and converting electronic signals into physical actions, respectively, enabling the system to interact with the physical world . The software is equally important,

The benefits of using open-source hardware and software in embedded systems design include cost-effectiveness, flexibility, and faster innovation. Open-source solutions lower costs by eliminating licensing fees and enabling reuse of existing components . They also allow for greater customization and flexibility, as developers can modify and adapt them to meet specific requirements . Open-source communities foster collaboration and idea sharing, resulting in innovative solutions and higher-quality products . However, there are limitations to using open-source technologies in embedded systems.
