Development of low-cost spectrometers based on embedded and mobile systems for chromium measurement in tanneries
Although commercial high resolution spectrometers exist, they are very expensive and the software requires the payment of licenses and cannot be adapted to certain measurement methodologies (eg X-ray fluorescence applied to mining, quality of drinking water and wastewater, food and others).
This project will develop low-cost high-resolution spectrometers based on different photonic sensors (CCD cameras incorporated in mobile devices and PDAs - Photodiode Array) with the use of embedded systems.
The developed spectrometers may be coupled to mobile devices (e.g. smartphones, tablets). An Android application will be developed with a user interface for the calibration, measurement and visualization of data from the CCD spectrometer of a mobile device. Also, an application based on a RaspberryPi embedded system with a wireless user interface for calibration, measurement and visualization of spectrometer data will be developed.
The devices developed will be validated and applied to a spectrophotometric method for the quantitative measurement of chromium in tannery liqueurs.
