Here's an example from Hong Kong, where some kids made a game and then built their own physical interface device and had a light sensor, so the light sensor detects the hole in the board, so as they move the physical saw, the light sensor detects the hole and controls the virtual saw on the screen and saws down the tree.

Can you turn off the light? Down.

The brighter the image at a given point on the sensor, the larger the value that is read for that pixel.

It was only with the development of the low cost integrated circuit that the Hall effect sensor became suitable for mass application.

Like here this is a very low light level actually.

When a fish swims underneath, a light goes on.

Neutral density A neutral density filter (ND filter) is a filter of uniform density which attenuates light of all colors equally.

Fajã de Baixo is a civil parish in the municipality of Ponta Delgada in the Portuguese archipelago of the Azores.

Each individual light sensor in the CCD reader is extremely small and because there are hundreds of sensors lined up in a row, a voltage pattern identical to the pattern in a bar code is generated in the reader by sequentially measuring the voltages across each sensor in the row.

And this is the water feeler.

It has just that sensor in it.

Use the color sensor to sample spot colors

Can I have the feeler here?

So, this does not have any sensors.

Each of these has a sensor.

So a ray of light could go down, be bent up into the observer's eye, and the observer sees a ray of light here.

The sensor is just a little strip of metal in that headband there.

The standard pressure sensor used a percussion cap to ignite it.

At low pH, the dye absorbs ultraviolet and blue light most strongly and appears yellow in solution.

Each sensor has its own lens and photosensitive cell(s).

These seismometers used damped horizontal pendulums.

You can see the little BB in the box is my tilt sensor.

her first night in the lab because she was going to make the sensor.

I just put it up because that little blue dot is the sensor.

MT Sensor PIC 1 F7AA97 2 x 8 PIC D50C3A

Because light specularly reflected from water does not usually reach the viewer, water is usually considered to have a very low albedo in spite of its high reflectivity at high angles of incident light.

Rezero keeps his balance by constantly measuring his pitch angle with a sensor.

The Nag Hammadi library is a collection of Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945.

This top light is I'm sorry if I'm making you seasick this top light is actually a water quality display that shifts from red, when the dissolved oxygen is low, to a blue green, when its dissolved oxygen is high.

This works with a laser sensor that's mounted on top of Rezero.

And you can use the tilt sensor to steer this car using this game.

The mine could then be removed carefully from the ground and the sensor easily unscrewed.

There's one called TOR, which is another nutrient sensor, like the insulin pathway.

It's really just a pressure sensor like the kind that's in a doorbell.

And it opens and closes the shutter so the amount of light coming out of the bottom which is made by the bacterium exactly matches how much light hits the squid's back, so the squid doesn't make a shadow.

Its sensor beams look both forward and backward at the same time, allowing it to do new exploration while it's still achieving geometric sensor lock on what it's gone through already.

The light grid will have a light, be lit up at night and give a kind of light ceiling.

We designed a network sensor, and kids would show up and refuse to leave the lab.

Reduce Uniform Noise Optimum settings for image noise due to sensors.

It has a feeler, where it can feel obstacles and turn around.

And Nike knows how to get your pace and distance from just that sensor.

As you would expect, it's a light, a desk lamp.

This kind of sensor is in the hit biometric device among early adopters at the moment the Fitbit.

The speed of the fan is measured by a rev counter and converted to a windspeed by an electronic chip.

A composite video audio cable, wired sensor bar and power adapter are also included.
