Sensor Technology Quiz

Which combination of sensors would best control the environment in a smart greenhouse?

• Temperature, Moisture, and Light Sensors

• Motion, Sound, and Proximity Sensors

• Pressure, Light, and Sound Sensors

• Humidity, Proximity, and Pressure Sensors

In a smart home security system, which sensor(s) would detect both motion inside and unusual sounds outside the house?

• Light and Temperature Sensors

• Sound and Motion Sensors

• Humidity and Proximity Sensors

• Pressure and Moisture Sensors

A temperature sensor is often used in air conditioning systems. Why does it need to capture data continuously?

• To maintain constant temperature adjustments

• To detect humidity changes

• To monitor air quality levels

• To detect physical movement in the room

Which sensor combination is ideal for monitoring road conditions for automated street lighting and traffic flow analysis?

• Temperature and Motion Sensors

• Light and Proximity Sensors

• Light and Motion Sensors

• Pressure and Humidity Sensors

An industrial robot in a factory uses a proximity sensor. What is the main function of this sensor in this context?

• To detect temperature fluctuations

• To sense the position of nearby objects

• To measure light intensity

• To record noise levels

Which sensor would NOT be useful for a system monitoring a weather station’s outdoor conditions?

• Humidity Sensor

• Sound Sensor

• Temperature Sensor

• Pressure Sensor

In a smartphone, which combination of sensors could detect the user's environment and adjust both screen brightness and orientation?

• Proximity and Temperature Sensors

• Motion and Light Sensors

• Humidity and Moisture Sensors

• Pressure and Light Sensors

A humidity sensor in an industrial environment needs to convert analog signals to digital. Why is this conversion necessary?

• Because digital data is easier to process by computers

• To improve signal strength

• To reduce humidity levels

• To measure temperature instead of humidity

Which sensor might be used in a vehicle’s airbag system to detect the sudden impact of a collision?

• Proximity Sensor

• Pressure Sensor

• Light Sensor

• Sound Sensor

In a security system, a motion sensor detects movement but does not distinguish between humans and animals. What might enhance its accuracy?

• Adding a light sensor to detect illumination levels

• Adding a temperature sensor to detect body heat

• Using a pressure sensor to monitor weight

• Using a moisture sensor to check the air’s water content
