Mobile system for measuring the color characteristics of objects
Journal Title: Електромагнітна сумісність та безпека на залізничному транспорті - Year 2017, Vol 1, Issue 14
Abstract
The article deals with the problem of creating a mobile device for measuring the color charac-teristics of both light sources and unlighted objects when illuminated with white light. The de-vice is based on the TCS230 sensor, which contains a matrix of photosensors with calibrated fil-ters, digital control and a digital output signal. Measured chroma signals are read by the micro-controller and transmitted via the Bluetooth module to a mobile device (smartphone, tablet) that works in the Android operating system. The developed application for the mobile device allows to receive information from the microcontroller through the radio channel, to calculate the color characteristics of the object, to visualize the measurement results, to store the results on the de-vice or to transmit via the Internet to the cloud services for further processing. The instrument was calibrated on standard lamps with known color temperatures, as well as measuring the color temperatures of energy-efficient lamps.
