What is the difference between capacitive and inductive sensors?
Inductive sensors use a magnetic field to detect objects. Capacitive sensors use an electric field. In order to be sensed by an inductive sensor an object must be conductive. This limits suitable targets to metal objects (for the most part). In order to be sensed by a capacitive sensor the target doesn't need to be conductive. A capacitive sensor will react to an object acting as a dielectric material as well as a conductive object. This makes metal and non-metal objects suitable targets.
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
What are photoelectric sensors used for?
Photoelectric sensors use light to detect the presence, absence, or distance of an object. They often use the infrared spectrum of light, though visible light is also used.
Which type of energy is it when we feel heat from the sun?
Radiant energy (light) - the heat you feel is "infra red" radiation. Your eyes can not see this wavelength of light but there are sensors (thermal sensors) in your skin that can feel it.
What describes the amplitude of a wave?
The square of the amplitude gives the intensity of the wave. Intensity in case of sound is sensed as loudness and in case of light as brightness.
Why are heat sensors located just under the epidermis?
so heat can be sensed faster
Why are sensors (or senses) necessary for behavior?
Stimuli must be sensed in order to produce a response.
Can anyone please tell what are the various sensors used in cars?
There are so many that making a list is impossible. Basically every function, movement, can and is sensed by the sensors.
Where are light sensors used?
light sensors are used in cars, televisions and computers. there are different types of light sensors.
What do light sensors do?
Light sensors measure the number of photons or the energy of light hitting the sensor.
What do light sensors measures?
Light sensors measure the number of photons or the energy of light hitting the sensor.
What are light sensors used for?
Light sensors are devices that are designed to detect light. There are several different types and styles of light sensors, each of them unique and having their own specific and useful uses.
Where is the eye light sensed and where it perceived?
The retina (rods and cones) senses the light and sends the information to the brain to be processed and perceived.
What are stop light sensor?
Stop light sensors are a loop of wire that is buried in the pavement and controls the traffic light. The sensors are able to detect the traffic that is waiting at the light.
How sensors are used?
Sensors are used to detect things, such as motion, light, or color.
What is meant by condition sensors?
I don't know, who am I? Einstein?
What type of sensors can garage doors have?
The main sensor used for garaged doors is a infrared line sensor. When the line of sight is broken the sensor is activated. Pressure sensors may additionally be implemented to stop the closing action if opposite pressure is sensed.
