TCS 3200 – Pin Diagram, Circuit and Applications

Color Sensor Module has 4 LEDs with TCS3200 Color Sensor IC.
The module is designed in such a way that 4 bright LEDs will light the object and reflections from that object will strike the TCS3200 Color Sensor IC to detect the color of an object.
TCS3200 is a programmable color-to-frequency converter, that gives square wave output with frequency directly proportional to the light sensitivity.
It consists of an 8×8 array of photodiodes i.e. 64 photodiodes.
Of the total 64 photodiodes, 16 photodiodes have Red filters, 16 photodiodes have Green filters, 16 photodiodes have Blue filters, and 16 photodiodes are Clear with No filters.
All photodiodes of the same color are connected in parallel.
This sensor gives us object color in form of RGB (Red, Green, Blue) values, from which we can define the object color.

Block Diagram and Pin Diagram

Pin 1:2 – S0:S1: Output frequency scaling selection pins.

These two pins are used to scale the frequency of the current to the frequency converter.

Pin 3 – OE (Active Low): Output Enable

Pin 4:5 – GND: VCC

Pin 6 – Output

This pin gives output in the form of a train of pulses. The duty cycle of these pulses is fixed to 50% and the frequency of these pulses is varying according to the input light.

Pin 7:8 – S2:S3 – Photodiode filter type selection pins

TCS3200 is applied for industrial process control.
In laser edge banding machines to detect color TCS3200 is used.
To detect chronic kidney diseases TCS3200 is used for urine analysis.
TCS3200 is used in fruit sorting systems.
The intensity of blue, red, and green radiations can be measured using this sensor module.
