Input devices MCQ — 1 Practice Questions with Answers

Explanation

Sensors are input devices that detect physical conditions such as temperature, moisture, pressure or light and send those readings to a computer or controller. A webcam captures images and video, so it is not meant for direct temperature or moisture readings. Scanners convert printed text or images into digital form, not environmental values. Joysticks are manual control devices used mainly for games, simulations or machine control. For measuring and feeding environmental data, sensors are the correct device.
