A webcam camera as an alternative cost-effective colorimetric sensor for the simple dual electrochemical – colorimetric detection system is proposed. Performance test of the system was investigated through electrochemical and colorimetric behaviors of redox reactions of potassium ferrocyanide complex. Image processing with two color systems, RGB and HSV, was applied together with various electrochemical techniques. Color responses obtained from the webcam correlated with electrochemical signals in various electrochemical techniques. The results from the proposed dual detection system agreed well with those obtained using conventional UV–vis spectroelectrochemical system reported previously. The application of proposed system was demonstrated for studying the redox reaction of catechin and electrochemical - colorimetric behaviors of Fe(II) and Fe(III) mixture. 2018-04-25T10:11:31Z 2018-04-25T10:11:31Z 2018-08-01 Journal 00399140 2-s2.0-85044661679 10.1016/j.talanta.2018.03.055 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85044661679&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/48366
