Senior Design

in my senior Design, my team and I decided to design and build a compact hydroponic greenhouse that is designed to be used by homeless communities, low-income communities, and big cities where there is not enough space to grow produce.

the greenhouse is designed to work on solar power and have the option to be plugged to the standard 120v Ac power source if it is available.

I am working on this project with another EE student, and we are still in the working on the project and expected it to be done before the end of the spring quarter of the academic year 2021-22.

My rule on this project was to help designing the electrical subsystem and to design and build a switch that would automatically switch the power source from the solar system to the 120v Ac source as soon as it connected to a power source to save the battery charge. I build the switch using two relays connected together. and when the system is plugged into 120v ac power source the relays would disconnect the system from the solar system and connect it to the 120v Ac.
