Which sensor is used by self driving vehicles Mcq?

Self-driving cars are loaded with ultrasonic sensors that measure the distance between vehicles and other objects.

Which of the sensor is used as position sensor Mcq?

Explanation: Proximity sensor is a non-contact type of position sensor. There are several type of proximity sensors that uses electromagnetic fields, light and sound for detection of the objects and their position.

What are sensors Mcq?

A Sensor is an electronic device that senses physical quantity in the form of pressure, temperature as input and translates it into electrical form using interfaced components like transducers. Classification of the sensor depends on the physical property the sensor measures.

Which of the following sensor is an example of passive sensor Mcq?

Camera with flash is an example for this process. In the case of passive remote sensing, it uses other source of energy.

What is a sensor in IoT Mcq?

This set of IOT Multiple Choice Questions & Answers (MCQs) focuses on “Proximity Sensor”. … Explanation: A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.

Which type of sensor is a tactile sensor Mcq?

Explanation: Touch sensors are also called as tactile sensor and are sensitive to touch, force or pressure. These are one of the simplest and useful sensors.

Why is proximity sensor used?

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. … Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing.

What are biosensors Mcq applications?

Biosensors are used in different fields as follows: Defense: To detect mustard gas, nerve gas, etc. Industry: To detect alcohol, acids, phenols, etc. Sports: To determine fatigue by measuring levels of lactic acid, ammonia in perspiration.

What is the use of the IR sensor Mcq?

What is the use of the IR Sensor? Explanation: The IR Sensor is used for calculating the distance between the sensor and the object.

WHAT IS sensor and instrumentation?

Development and optimisation of new or existing devices that detect and measure changes in temperature, pressure, vibration and light, for instance, and integration and optimisation of these devices into a new system or instrument.

Is a satellite a sensor?

Satellite sensors that measure infrared radiation infer the amount of heat emitted from an object at the Earth’s surface. Objects with an average earth temperature (roughly − 50° to 50°C, or − 58° to 122°F) emit most of their energy in the infrared region.

Are passive sensor used?

Passive sensors can only be used to detect energy when the naturally occurring energy is available. For all reflected energy, this can only take place during the time when the sun is illuminating the Earth. … The radiation reflected from that target is detected and measured by the sensor.

Which of the following is passive sensor?

A passive sensor is a device that detects and responds to some type of input from the physical environment. … Examples of passive sensor-based technologies include: Photographic, thermal, electric field sensing, chemical, infrared and seismic.

Which devices measures gases or liquid Mcq?

Which devices measures gases or liquid? Explanation: The pressure sensor is a device for pressure measurement of gases or liquid.

Which type of sensor is used to measure the distance between the vehicle and other objects in its environment?

Ultrasonic sensors can measure the distance to a wide range of objects regardless of shape, color or surface texture. They are also able to measure an approaching or receding object. By using “non-contact” ultrasonic sensors, distances can be measured without damage to the object.

Which type of sensor is used to measure the distance between the vehicle and other objects in its environment Mcq?

Self-driving cars are loaded with ultrasonic sensors that measure the distance between vehicles and other objects.
