Implementation of a Temperature Monitoring System Utilizing Cortex-M3 with I2C-Based Sensor Integration

The work focuses on designing and implementing a smart home system using the Inter-Integrated Circuit (I2C) protocol for seamless sensor integration with the ARM Cortex M3 microcontroller. The system utilizes the ARM Cortex-M3, i.e., LPC1768 architecture to facilitate efficient embedded systems development. The I2C protocol, with its synchronous, multi-master, and multi-slave communication capabilities, enables data exchange between integrated circuits with minimal wiring complexity. The project demonstrates the integration of temperature sensors, showcasing real-time environmental monitoring and control. The master-slave architecture of I2C allows for adding and removing devices, enhancing the system’s adaptability. A key highlight of the work is its demonstration of temperature sensor LM75A integration, enabling real-time environmental monitoring. The hardware prototype model successfully interfaces sensors with the LPC1768 microcontroller, leveraging the I2C protocol for reliable and efficient communication.
