Incubation Station for the Bacterial Growth Study in Biological Samples

Abstract

This work shows the designing and characterization of a prototype of laboratory incubator as support of Microbiology research, in particular for the research of the bacterial growth in biological samples through optic methods (Turbidimetry) and electrometric measurements of bioimpedance. It shows the results of simulation and experimentation of the design proposed for the canals of measurement of the variables: temperature and humidity, with a high linearity from the adequate selection of the corresponding sensors and the analogue components of every canal, controlled with help of a microcontroller AT89C51 (ATMEL) with adequate benefi ts for this type of application.
