7.1.3 - Evaluate different input devices for the collection of data in specified situations. Flashcards
What are some common input devices used in control systems?
Common input devices include a mouse, keyboard, joystick, light pen, touch pad, microphone, scanner, track ball, and camera.
What is assistive technology in relation to input devices?
Assistive technology refers to input devices designed to help people with disabilities operate computer hardware and software, ensuring accessibility.
What is the purpose of a heat sensor, and where is it used?
A heat sensor measures temperature and is used in systems like central heating or fire alarms to monitor and control temperature levels.
What does a humidity sensor measure, and in which environments is it useful?
A humidity sensor measures the water vapor in the air and is useful in environments like greenhouses and swimming pool halls to maintain optimal conditions.
What does an infrared sensor measure, and where is it applied?
Infrared sensors measure radiation and are often applied in alarm systems to detect movement or heat signatures.
Where is a light sensor used, and what does it measure?
A light sensor measures brightness and is commonly used in streetlights and security lighting systems to adjust based on ambient light levels.
What is the function of a pH sensor, and where might it be used?
A pH sensor measures the acidity or alkalinity of a substance and is used in environmental monitoring to assess water quality or soil conditions.
What are pressure sensors used for, and in what applications?
Pressure sensors measure force applied to them and are used in automatic doors, alarms, and elevator systems to detect movement or weight.
What does a smoke sensor detect, and in what scenarios is it crucial?
A smoke sensor detects particles in the air and is crucial in fire alarm systems to identify the presence of smoke, signaling potential fire hazards.
What does a sound sensor measure, and where is it typically used?
Sound sensors measure sound pressure levels and are used in noise pollution monitoring systems to evaluate environmental sound levels.
Where might a tilt sensor be used, and what does it measure?
Tilt sensors measure the angle of tilt and are used in systems like aircraft or window alarms to detect changes in angle or position.
What is the difference between touch and pressure sensors?
Touch sensors are more sensitive and detect contact, while pressure sensors measure force. Touch sensors are often used in robots and devices requiring sensitive input.
