TCS3200 Color Recognition Sensor Module
This Arduino compatible TCS3200 color sensor module consist of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The main part of the module is the TCS3200 chip which is a Color Light-to-Frequency Converter. The white LEDs are used for providing proper lighting for the sensor to detect the object colour correctly. This chip can sense a wide variety of colours and it gives the output in the form of corresponding frequency. This module can be used for making colour sorting robots, test strip reading, colour matching tests etc. (find out a wide range of Sensor at solicstores.in)
The TCS3200 chip consist of an 8 x 8 array of photodiodes. Each photodiode have either a red, green, or blue filter, or no filter. The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal circuits includes an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.
Four white LEDs provide plenty of light for the color sensor and allow you to use the module in any ambient light.
The module requires only a single supply voltage between 2.7V and 5.5V – making it compatible with nearly all common microcontrollers.
|GND||4||Power supply ground. All voltages are reference to the ground.|
|OE||3||Enable for FO (Active low)|
|OUT||6||Output frequency (fo)|
|S0, S1||1, 2||Select lines for output frequency scaling|
|S2, S3||7,8||Select lines for photodiode type.|
|S0||S1||OUTPUT FREQUENCY SCALING(f0)|
The Photodiode type pins allow you to pick which color light you are currently detecting:
|H||L||CLEAR (NO FILTER)|
The sensor has four different types of filter covered diodes. In the 8 x 8 array of photodiodes, 16 photodiodes have Red filters, 16 have Blue filters, 16 have Green filters and the rest 16 photodiodes are clear with no filters. Each type can be activated using the S2, S3 selection inputs. Since each photodiodes are coated with different filters each of them can detect the corresponding colours. For example, when choosing the red filter, only red incident light can get through, blue and green will be prevented. By measuring the frequency, we get the red light intensity. Similarly, when choose other filters we can get blue or green light.
We can also set the frequency scaling option by using the S0, S1 select lines. Normally, in Arduino 20% frequency scaling is used.
