Display device for colorimetric sensor

Abstract

The colorimetric reaction analysis method is used to identify or determine the concentration of a compound in any solution. The colorimetric examination is the most generally perceived method of the various number of methods which are used to measure and can be seen by the human eye viably as it falls in the noticeable range of the spectrum. At present, colour detecting devices are mainly for those that detect colours of solids with limited accuracy. This research is to improve the detection accuracy and to make a device adaptable for liquid colour detection. This experiment utilizes a technique to construct light ways and utilizes TCS3200 colour sensor (light to frequency convertor) and Node MCU (Node MicroController Unit). The TCS3200 colour sensor comprises of a photodiode and a current-frequency converter. The hardware equipment was tested for a colour change from blue to red for a general arrangement in which the colour has a transition from blue to red. The output from the TCS3200 colour sensor was noted for blue, green and red colour. The outcomes demonstrated that the sensor was effectively able to identify and separate the various colours. In this manner making it a basic and accurate detecting gadget. In this way it has extensive development and various application prospects, and also can be broadly utilized in science and its different fields.
