Research of Urine Analyzer Based on Color Sensor

Abstract

Urine analysis is used in clinical medicine diagnosis method. In this paper, we introduce the urine analyzer working principle. Using the color recognition sensor chip, we design a fast urine analyzer, which is mainly constituted by several parts: LCD, keyboard control, serial communication, network interface, print, ARM Control unit, sample of sensors, motion control, color capture, brightness control, etc. we studies the test strip tests, the specific gravity of testing theory, the test principle of the turbidity , the color test, the principle of color sensor and gives a the flow chart of color test subprogram.

An LDR Based Colour Sensor for Urine Analysis: A Review

“…This involves the integration of colour balancing functions in smartphone cameras. In the report by [29], the authors also employed the use of smartphones in performing colourimetric analysis, discussing smartphone-based biochemical sensors, smartphone-based imaging biosensor, smartphone-based Immuno biosensor, smartphone-based hybrid biosensor as five types of smartphone-based microfluidic biosensing system at the point-of-care detection, which is applicable in urine analysis. The report in [30] investigated colourimetric biosensors, which employ the use of smartphones as detectors, and a computer analyzed the sample and sent the result back to the smartphone.…”

A portable analyzer based on a novel optical structure for urine dry-chemistry analysis

“…In this way, the mono-chromaticity, the assembled position and the irradiation angles of LEDs have a great impact on the test results. In the second way, when the white light illuminate each URP in proper order, the corresponding color value can be collected by the color sensor [10]. Though this method is useful to enhance testing accuracy of semi-quantitative analysis, both the assembled position and the angle of white-light source also have a great effect on the test results [11].…”
