Abstract :
An efficient and portable photoacoustic multi-gas monitor for biomedical application is needed in hospital in order to protect the health of workers, patients and, somewhat, visitors. If highest precision is not required, especially for continuous monitoring of anaesthetic gases, a LED (light emitting diode) based-detecting system can be employed in order to estimate an attention threshold level of gas. But when a gas purification facility is used in order to exhaust biomedical gas present in a surgery room, it can be suitable to employ a different sensing technology to reduce costs and to increase efficiency, since the quality and the quantity of gases decrease, a new affordable instrumentation based on LED technology is proposed in the present research. The idea behind this work is to control LED sources by a cheaper system in other to get acceptable results that are valid for an interesting range of frequencies. Particular care has been given to conditioning subsystem because of mixing RGB colours.
