ozone, beer-lambert, LED UV, 3D Printing, PSoC 5


In this work the design and manufacture of a prototype of an ozone measuring device is presented. One of the goals of this design is to develop an easy and fast way to manufacture these kind of devices, that might also be used for other gases. The method used to measure the ozone is the Beer´s Lamberth Law. Readily available materials are used. An UV LED was used as a source, and a photodiode as a detector. For the air-light interaction an absorption cell was necessary, it was made of Polylactic Acid and manufactured in a 3D printer. In the microcontroller the operational amplifiers and the signal processors were implemented in a PSoC 5. Good performance of all components, both electronic and 3D printed, was observed. Measurements were achieved in a range of 0 to 100 ppm with an accuracy of ± 5 ppm.

En este trabajo se presenta el diseño y la fabricación de un prototipo para medición de ozono, en el cual se utilizan materiales de fácil adquisición. El propósito de este diseño es proporcionar una alternativa robusta y menos costosa de fabricar un dispositivo de medición de ozono que puede ser extendida a otros gases. El método de medición se basa en la Ley De Beer-Lamberth. Se utiliza un LED (light-emitting diode) UV como fuente y un fotodiodo como detector de luz. La muestra de aire interactúa con la luz en el interior de una celda de absorción, fabricada en una impresora 3D usando como material PLA (Polylactic Acid). La amplificación y el procesamiento de la señal, se realizaron mediante una tarjeta electrónica PSoC (Programable System on Chip). Se observó un buen comportamiento de todos los componentes, tanto electrónicos como impresos 3D. Se lograron realizar mediciones en un rango de 0 a 100 ppm con una exactitud de ± 5 ppm.
