STEM Principle 1: Science
STEM Principle 1: Science
The connection to the project problem: Our project deals with two major science concepts: electricity and motion detection. We will need to research the basics of electricity to get our design to work, and implementing a sensor brings a lot more science into the design. Motion detection works in many different ways, depending on the method, ours being a PIR sensor. PIR stands for passive infrared, which detects infrared radiation emitted by warm objects. This allows the sensor to detect body heat to trigger the light to turn on. We will also need to have an understanding of how electricity flows through a circuit for it to work. Our project has electricity as a main focus, and the conversion from electrical energy to light energy is a core science concept for what we're doing.

Relation to design specifications: One of our design specifications was for the light to be bright enough to illuminate the contact points on the outlet, which can be achieved if we use electricity to convert electrical energy to light energy.

The connection to the project problem: There is a lot of technology involved in our project, including circuits and motion-detecting technology. Our project involves LED lights, which are commonly used to increase energy efficiency and reduce heat output. Another piece of technology is the PIR sensor, which is a type of motion-detecting technology that detects body heat. Our project implements both electrical and motion-detecting technology to successfully illuminate the outlet.

STEM Principle 3: Engineering
The connection to the project problem: The principles of engineering are crucial to ensuring that we are the most efficient in our work as we can be. This project utilizes the design process, which is very common in the field of engineering. All phases of the design process are important to this project, such as brainstorming ideas that allowed us to come up with the design that we did. The design process also includes prototyping and testing, which allows us to make changes as necessary to improve our design.

STEM Principle 4: Math
The connection to the project problem: Simple math is used in multiple areas of our project. One of the ways we will use math is the dimensions of everything, and making sure it fits in the outlet. We are also using math for the electrical and coding elements. We'll have to use Ohm's law to calculate the voltage, current, and resistance. We will also be using math for the timing of the light, making it turn off after a certain amount of time using simple code.
Relation to design specifications: We'll need to do testing and documentation to ensure our design fits the design specifications. If it doesn't, we'll have to brainstorm ways to make it adhere to the constraints and requirements.
