Sensors and Control Systems Quiz

Pauses the program execution for a specified duration.

Sets the voltage of a pin to HIGH.

Sets the voltage of a pin to LOW.

Initializes the input and output pins of the GPIO.

Sets the specific pin as either an input or output.

Clears all the input and output pins of the GPIO.

Generates a signal with varying pulse width, used for controlling analog devices.

A device that receives data from a computer, such as a keyboard or mouse.

A device that displays or transmits data from a computer, like a monitor or printer.

A device that measures an analog quantity and converts it to a digital signal.

A device that outputs a digital signal, typically using a built-in ADC.

A switch that activates when pressed and deactivates when released.

A switch that detects the presence of an object and acts as a limit on the range of motion.

A sensor that measures the intensity of light.

A sensor that detects the temperature of its surroundings.

Type of temperature sensor where resistance decreases as temperature increases.

A device that measures changes in electrical resistance caused by deformation.

A sensor that converts mechanical force or tension into an electrical signal.

A sensor that measures pressure by converting it into an electrical signal.

A type of pressure sensor that uses changes in resistance to measure pressure.

A sensor that detects and translates sound levels into an electrical signal.

A sensor that measures distance by emitting sound waves and calculating the time it takes for the waves to return.

A control system that uses feedback to maintain a desired output value.

The measured parameter that needs to be controlled, like temperature or pressure.

The desired value for the process variable.

The difference between the process variable (PV) and the set point (SP).

A controller that uses proportional, integral, and derivative terms to calculate control output.

A controller that adjusts its output based on the current error. The larger the error, the stronger the correction.

The time it takes for the process variable to rise from 10% to 90% of its final value.

The maximum amount the process variable overshoots its final value during a control action.

A structured process for creating a plan for a building system before it is built, taking into account functionality, efficiency, and aesthetics.

The first step in the design process, which involves researching existing solutions and identifying potential problems and successes.

The most crucial part of the design process, specifying the desired functionality and solving the intended problem. These requirements are based on customer needs and internal specifications.

The phase of the design process where several ideas are generated and analyzed to determine their feasibility and potential for implementation.

A crucial step in the design process, where the design's potential is evaluated to determine if it is achievable and within cost constraints.

The final phase of the design process where the design is fully developed and implemented.

Statements in the requirements document that describe mandatory features of the design.

Statements in the requirements document that declare facts related to the design.

A stage in the product development process focused on minimizing errors, managing costs, evaluating risks, and assessing the chances of success for the intended project.

A technique used to compare and evaluate different design concepts, assigning weights based on importance and scores based on how well each concept meets requirements.

The evaluation process ensuring that a product, service, or system meets the defined specifications.

The evaluation process assessing whether the product or system fulfills the user's operational needs.

The stage where plans for mass production are made, including decisions on manufacturing processes and tools.

The costs incurred before production begins, such as investments in tools, equipment, facilities, and initial setup.

The costs associated with the manufacturing process itself, varying depending on the number of units produced.

A decline in a product's usefulness due to factors other than physical deterioration, effectively shortening its lifespan.

A situation where a product becomes unusable or outdated due to advancements in technology.

When a product loses its usefulness because the owner's needs have changed.

When a product becomes unfashionable or undesirable due to changes in aesthetics.

When a product becomes uneconomical to use or maintain due to more efficient alternatives.

When a product is banned or made illegal to use due to legal regulations or restrictions.

A state where the risks to people and equipment are minimized during the operation of mechatronic systems.

Common hazards in mechatronics include electrical shocks, short circuits, and potential fires.

The ideal safety level for a product is a balance between low risk and high safety, and high risk and low safety.
