Systems Approach to Designing Quiz

A pressure sensor detects changes in pressure within a system and provides input to a microcontroller, which can use this information to trigger actions, such as activating an alarm or controlling a device.

A light sensor detects the level of light in an environment and converts this information into a signal that can be processed by a microcontroller. It can be used to adjust lighting or activate other devices based on ambient light levels.

A switch is used to control the flow of electricity in a system. It can either open or close a circuit, turning devices or processes on or off.

A microcontroller can count events, such as the number of times a sensor is triggered. This count can be used to control the operation of other components or to keep track of time-dependent actions in a system.

A microcontroller can be programmed to make decisions based on input from sensors. For example, it could decide to turn on a fan if the temperature sensor detects a high temperature, or activate a light if the light sensor detects low light levels.

A timer can be used to delay actions, control the duration of an event, or trigger an action after a specific time interval, such as turning off a lamp after a certain period.

A buzzer can be used to alert users when a sensor detects an event, such as when a door is opened or a temperature threshold is exceeded, providing an audible warning or notification.

A speaker can be used to produce sound or music when activated by a microcontroller. For example, it might play a sound when a sensor detects motion, or when a timer expires, providing feedback to the user.

A lamp can be used as an output device to provide visible feedback. For example, it might light up when a light sensor detects insufficient light, or it could be turned on or off based on temperature or pressure readings.

Inputs are the data or signals received from sensors (e.g., light, temperature, pressure). The process involves using a microcontroller to process these inputs, make decisions, and perform actions. Outputs are the resulting actions, such as activating buzzers, speakers, or lamps, to provide feedback or control devices.
