Sensor óptico #

Introducción #

El sensor óptico detecta el color, el brillo y la presencia de objetos cercanos mediante una combinación de un sensor de color RGB y un sensor de proximidad. También puede usar su LED integrado para iluminar los objetos y lograr una detección más precisa.

El sensor óptico VEX.

A continuación se muestra una lista de los bloques disponibles:

configurar luz óptica – Enciende o apaga el LED del sensor óptico.
set Optical light power – Sets the power level of the Optical Sensor’s LED.
Optical found an object – Reports whether the sensor is detecting an object within range.
Optical detects color – Reports whether the Optical Sensor detects a specified color.
Optical brightness – Reports the brightness detected by the Optical Sensor.
Optical hue – Reports the hue detected by the Optical Sensor.
when Optical – Runs the attached stack of blocks when the Optical Sensor detects or loses an object.

set Optical light #

The set Optical light stack block turns the Optical Sensor’s LED on or off. This can help increase the sensor’s accuracy when detecting colors.

conjunto [Optical 1 v] luz [encendido v]

Parámetros	Descripción
dispositivo	Which Optical Sensor to use, configured in the Devices window.
estado	The state of the Optical Sensor’s light: on or off.

cuando empezó
[Turn on the sensor's LED.]
conjunto [Optical 1 v] luz [encendido v]

ajuste de potencia de luz óptica #

The set Optical light power stack block sets the brightness of the Optical Sensor’s LED. The light can help the Optical Sensor detect objects and colors more clearly.

A higher percentage makes the light brighter. A lower percentage makes the light dimmer.

If the Optical Sensor’s light is off, setting the light power above 0% will turn the light on.

If the Optical Sensor’s light is on, setting the light power at 0% will turn the light off.

Establezca la potencia de luz [Optical 1 v] al [50]%

Parámetros	Descripción
dispositivo	Which Optical Sensor to use, configured in the Devices window.
brillo	The brightness to set the Optical Sensor’s light to, from 0% to 100%. Use whole numbers.

cuando empezó
[Turn on the sensor's LED at half brightness.]
Establezca la potencia de luz [Optical 1 v] al [50]%

Optical found an object #

The Optical found an object Boolean block reports whether or not the Optical Sensor detects an object within range.

True — The Optical Sensor detects an object.
False — The Optical Sensor does not detect an object.

<[Optical 1 v] Encontraste un objeto?>

Parámetros	Descripción
dispositivo	Which Optical Sensor to use, configured in the Devices window.

Ejemplo

Avanza hasta que se detecte un objeto.#

cuando empezó
[Drive forward until an object is found.]

Optical detects color #

The Optical detects color Boolean block reports whether the Optical Sensor detects a specified color, based on the detected hue value.

True – The sensor detects the specified color.
False – The sensor does not detect the specified color.

Note: The Optical Sensor is looking for hue ranges that match the specified color. For detecting specific hue ranges, see the Optical hue reporter block.

<[Optical 1 v] detecta [rojo v]?>

color

Which color to look for:

red – A detected hue value between 340° - 20°.
green – A detected hue value between 80° - 140°.
blue – A detected hue value between 200° - 240°.
yellow – A detected hue value between 40° - 60°.
orange – A detected hue value between 20° - 40°.
purple – A detected hue value between 240° - 280°.
cyan – A detected hue value between 140° - 200°.

Brillo óptico #

The Optical brightness reporter block reports how much light is reflected back to the Optical Sensor, as a percentage from 0% to 100%.

A higher percentage means more light is reflected back to the Optical Sensor. A lower percentage means less light is reflected back.

Tonalidad óptica #

The Optical hue reporter block reports the hue detected by the Optical Sensor as a number from 0 to 359 degrees.

Hue is a way to describe color using numbers around a color wheel.

cuando óptico #

The when Optical hat block runs the attached stack of blocks whenever the Optical Sensor detects or loses an object.

cuando [Optical 1 v] [detects v] un objeto :: hat events

Parámetros	Descripción
dispositivo	Which Optical Sensor to use, configured in the Devices window.
estado	When the attached stack of blocks will run: detects runs when an undetected object is detected, while loses runs when a detected object is now no longer detected.
