What does a sensor do 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 type of sensor is a tactile sensor Mcq?
Touch sensors
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.
What is the humidity sensor Mcq?
3. What is humidity sensor? Explanation: A hygrometer is an instrument used for measuring the water vapor in the atmosphere. Humidity measurement instruments usually rely on measurements of some quantity such as temperature, pressure, mass or a mechanical or electrical change.
Is correct for proximity sensors Mcq?
Which of the following is correct for proximity sensors? Explanation: Proximity sensors may be of capacitive, inductive or ultrasonic type.
What is the role of a sensor in an IoT device?
Sensors play an important role in creating solutions using IoT. Sensors are devices that detect external information, replacing it with a signal that humans and machines can distinguish.With the expansion of the fields in which sensors play an important role, the market is still growing with a variety of sensors.
What is the purpose of sensor?
A sensor is a device that produces an output signal for the purpose of sensing of a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor.
Why sensor can be used to measure distance in robots Mcq?
Which sensor can be used in robots for measuring distance? Explanation: Ultrasonic Sensor can be used in robots for measuring distance. This sensors use ultrasonic sound for measurement of distance. It constitutes of ultrasonic wave producer and a receiver.
What is the role of sensors in the smart grid architecture of IoT?
What is the role of Sensor in smart grid architecture of IoT? Explanation: Sensors and Actuators are connected, send data when needed, secure and low power, easy to install and configure. Integration communication capability.End to End Security from Sensor to Cloud.
Which type of sensor is a tactile sensor?
A common application of tactile sensors is in touchscreen devices on mobile phones and computing. Tactile sensors may be of different types including piezoresistive, piezoelectric, optical, capacitive and elastoresistive sensors.
What is humidity sensor?
A humidity sensor is a device that detects and measures water vapor. TE Connectivity (TE) manufactures a complete range of calibrated and amplified RH sensor products to measure relative humidity.
Which one is a humidity sensor?
There are three basic types of humidity sensors: capacitive, resistive and thermal. All three types will monitor minute changes in the atmosphere in order to calculate the humidity in the air. A capacitive humidity sensor measures relative humidity by placing a thin strip of metal oxide between two electrodes.
Which devices measures gases or liquid?
Which devices measures gases or liquid? Explanation: The pressure sensor is a device for pressure measurement of gases or liquid. Pressure is an expression of the force required to stop a fluid from expanding.
What are sensors explain with example?
Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically. Let’s explain the example of temperature.
Why is proximity sensor used?
A proximity sensor is a device that can detect or sense the approach or presence of nearby objects and for this it does not need physical contact. There are different kinds of proximity sensors. Some of them are listed [8]: Inductive: This type of sensor is used to detect nearby metallic objects.
Which of the following are examples of sensors?
List of Sensors
- Vision and Imaging Sensors.
- Temperature Sensors.
- Radiation Sensors.
- Proximity Sensors.
- Pressure Sensors.
- Position Sensors.
- Photoelectric Sensors.
- Particle Sensors.
What is a sensor technology?
What is Sensing Technology?And sensing technology, simply put, is a technology that uses sensors to acquire information by detecting the physical, chemical, or biological property quantities and convert them into readable signal. There are a wide variety of sensors available for practically any industrial need.
What is IoT sensor data?
Modern IoT Sensors & Data Capture
Sensors are measuring just about any aspect of the physical world. The calibration of sensors allows them to be tailored to application-specific functions, so they can measure things like temperature, vibration, electricity, and air composition with accuracy.
WHAT IS sensor and its classification?
All types of sensors can be basically classified into analog sensors and digital sensors. But, there are a few types of sensors such as temperature sensors, IR sensors, ultrasonic sensors, pressure sensors, proximity sensors, and touch sensors are frequently used in most electronics applications.
Which of the following sensor is used to measure the distance Mcq?
Clarification: Ultrasonic sensor should one prefer for accurate measurement of distance upto 1 meter. Infrared sensor can also be used for measuring distance but its range is less than a meter.
Why do the robot need sensor?
Robots need to use sensors to create a picture of whatever environment they are in. An example of a sensor used in some robots is called LIDAR (Light Detection And Ranging).Lasers illuminate objects in an environment and reflect the light back. The robot analyzes these reflections to create a map of its environment.
