Colour Sensor  (Light to Frequency Converter)

The TCS3200 programmable color light-to-frequency converters that combine configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance).

Features:

1. High resolution conversion of light intensity to frequency.
2. Programmable colour and full scare output.
3. Direct communication with microcontroller.
4. Single supply 3V-5V
5. Power down feature.
6. stable temperature coefficient.
