INTRODUCTION

Colour detection based chemical sensing is mostly implemented with particular emphasis on colorimetric sensors because many parameters, like pH concentration, and chemical gases can cause direct or indirect colour changes in biological and chemical species. 
Optical sensors usually have a non-linear relationship between the sensor’s response and the effect to be sensed or the measured. Due to the fact that optical sensors have highly sensitive and non-linear nature, an unexpected change in the measured may cause considerably changes and measurement errors in the sensor’s responses. Furthermore, it is expected that in modern sensor technology, a sensor has to adapt itself to the changing or unexpected conditions. 
All parts of the sensor consist of easily available components. For example, the reflected signal from colored surface is produced by a RGB LED driven by a microcontroller and is detected by a photodiode. The analog signal from the photodiode is then amplified by an Op-Amp and applied to the microcontroller where it is converted to digital signals and processed.
