color_ir_sensor — Color IR Sensor

The main functionality and function of the color_ir_sensor module

Color infrared sensor description

As shown in the figure, the sensors in front of the rocky are

• White LED：light white to achieve detecting the visible light reflection intensity on the surface of the object with using visible light sensor.
• Visible Light Sensor：detect the visible light intensity.
• RGB LED：light LED with specific RGB value to achieve recognizing the color with using the visible light sensor.
• Infrared Light Sensor：detect the infrared light intensity
• Infrared Transmitter：transmit infrared light to achieve detecting the infrared light reflection intensity on the surface of the object with using the infrared light sensor.

Function

color_ir_sensor.get_red()

Get the size of the red color component of the color sensor, parameter range is 0 ~ 100.

color_ir_sensor.get_green()

Get the size of the green color component of the color sensor, parameter range is 0 ~ 100.

color_ir_sensor.get_blue()

Get the size of the blue color component of the color sensor, parameter range is 0 ~ 100.

color_ir_sensor.is_color(color_str)

Judge whether a matching color is detected, parameters：

• color_str color type, including red, green, blue, yellow, cyan, purple, white, black, the corresponding parameter is red, green, blue, yellow, cyan, purple, white, black. Return value is boolean, Ture represents color matching, False represents the colors do not match.

color_ir_sensor.get_light_strength()

Get the ambient light intensity detected by the visible light sensor, parameter range is 0 ~ 100.

color_ir_sensor.get_greyness()

Get the grayscale value detected by the visible light sensor (using RGB LED and visible light sensor), parameter range is 0 ~ 100.

color_ir_sensor.get_reflected_light()

Get the visible light reflection intensity detected by the visible light sensor, parameter range is 0 ~ 100.

color_ir_sensor.get_reflected_infrared()

Get the infrared light reflection intensity detected by the infrared light receiving tube, parameter range is 0 ~ 100.

color_ir_sensor.is_obstacle_ahead()

Detect if there are obstacles in front, the return value is boolean, Ture represents obstacles, False represents no obstacles.

color_ir_sensor.set_led_color(color_name)

Set color for the RGB LED light of the color sensor, parameters：

• color_name including red, green, blue, yellow, cyan, purple, white, black, the corresponding parameter is red, green, blue, yellow, cyan, purple, white, black.

Sample Code：

import codey
import rocky

while True:
    if rocky.color_ir_sensor.is_obstacle_ahead():
        rocky.color_ir_sensor.set_led_color('white')
    else:
      rocky.color_ir_sensor.set_led_color('black')
