Exploring EV3 IR Sensor Concepts

What does the IR sensor in the EV3 kit primarily detect?

• Sound waves

• Infrared light

• Water vapor

• Magnetic fields

Which EV3 sensor is used to detect signals from the beacon?

• Touch Sensor

• Color Sensor

• IR Sensor

• Gyro Sensor

What is the main function of the EV3 beacon?

• To measure temperature

• To emit infrared signals

• To play sounds

• To display colors

In EV3 programming, which block is used to read the distance from the IR sensor?

• Move Steering Block

• Sound Block

• IR Sensor Block

• Display Block

How does the IR sensor help in obstacle detection?

• By measuring sound reflection

• By detecting changes in light intensity

• By measuring the amount of reflected infrared light

• By sensing temperature changes

Which EV3 programming concept allows the robot to repeat actions until the beacon is detected?

• Switch Block

• Loop Block

• Math Block

• Wait Block

Which of the following is NOT a mode of the EV3 IR sensor?

• Proximity mode

• Beacon mode

• Remote mode

• Color mode

If the IR sensor reads a proximity value of 100, what does it mean?

• Object is very close

• Object is very far

• Beacon is detected

• Sensor is off

Which block would you use to make the EV3 robot move towards the beacon?

• Display Block

• IR Sensor Block

• Move Steering Block

• Sound Block

How can you integrate the IR sensor with motors in EV3 programming?

• By connecting the sensor to the motor port

• By using sensor values to control motor actions in the program

• By attaching the sensor physically to the motor

• By using the color sensor block
