This IoT project focused on developing an automated irrigation system that monitors soil moisture levels and activates a water pump when necessary. The system ensures that plants receive the optimal amount of water by constantly monitoring soil moisture, reducing the risk of under- or over-watering.

The project included the integration of off-the-shelf soil moisture sensors to measure soil moisture levels, as well as the integration of a water pump and control system to automate the… Show more

This IoT project focused on developing an automated irrigation system that monitors soil moisture levels and activates a water pump when necessary. The system ensures that plants receive the optimal amount of water by constantly monitoring soil moisture, reducing the risk of under- or over-watering.

The project included the integration of off-the-shelf soil moisture sensors to measure soil moisture levels, as well as the integration of a water pump and control system to automate the irrigation process. This necessitated a combination of hardware and software development, as well as extensive testing and optimization of the system.

This project provided me with valuable experience in IoT, sensor integration, and hardware and software development for control systems. I also gained a better understanding of the importance of precise irrigation in plant growth and the potential benefits of agriculture automation. Show less

This project focused on optimizing the boundary scan test instructions of the STM32F103C8T6 microcontroller by creating a user-friendly command-line interface. The goal was to facilitate testing and improve the accuracy of circuitry testing for JTAG devices.

Specifically, the project aimed to detect possible faults in the circuitry, such as Stuck-at faults and open circuits, using the PRELOAD and EXTEST instructions. By doing so, we were able to verify the functionality of the I/O pins… Show more

This project focused on optimizing the boundary scan test instructions of the STM32F103C8T6 microcontroller by creating a user-friendly command-line interface. The goal was to facilitate testing and improve the accuracy of circuitry testing for JTAG devices.

Specifically, the project aimed to detect possible faults in the circuitry, such as Stuck-at faults and open circuits, using the PRELOAD and EXTEST instructions. By doing so, we were able to verify the functionality of the I/O pins and ensure that the device was functioning properly.

The project involved extensive testing and optimization of the test instructions, as well as the development of a streamlined and user-friendly interface. Through this work, I gained valuable experience in software development, testing, and project management, while deepening my understanding of circuitry testing and JTAG devices. Show less
