RGB Color Sensor
Hardware Manual Rev 1r0
FEATURES • Power requirement: 7 – 9VDC power supply or ba�ery. • Controller: Z8E04 MCU • Color memory: up to 3 colors can be stored • User interface: 3 push bu�ons. 1 for each color memory • Outputs: 3 logic outputs. 1 for each color
RGB Color Sensor detects color by measuring how much light is reflected by the object under test us-ing red, green, and blue light source. Color tolerance is preset to 12% and is capable of detec�ng wide range and shades of colors. Internally stores up to three color profiles corresponding to its three Go-NoGo digital outputs.
Microcontroller based sensor capable of detec�ng object of desired color. Can store up to 3 differ-ent colors and has 3 individual logic output for each se�ng. Se�ng of desired color can be done easily thru simple push bu�on ac�on.

MAJOR COMPONENTS PRESENTATION
Figure 1. RGB Color Sensor & its major components
PARTS DESCRIPTION:
Power LED - lights up when a supply voltage is presentLED 1, 2 & 3 - lights up individually when object’s color is the same or near the SET COLOR for each LED.Error LED - lights up when the sensor is saturated for that specific color being test. Also lights up at the ab-sence of an object.Switch 1, 2 & 3 - Use to set desired color. Push un�l corresponding LED blinks then release to set desired color. The corresponding LED will lights up indica�ng that the present color was set successfully.Output Port - each color have 1 logic output.VCC Port - for 7V-9V power supply or ba�ery.U2(Z8EO4 MCU) - microcontroller capable of detec�ng object of desired color.Color Sensor - act as input, and sense and register specific color.

Figure 2. RGB Color Sensor Connected to a microcontroller with Color LCD Shield
To start, put a power supply in the ‘VCC’ port. Put the object on the RGB LED and Color sensor then press the chosen color registra�on bu�on(S1, S2, or S3) un�l the colored LED blinks (Indica�on of color registra�on), do the said process 3 �mes using different push bu�ons.
