In this work they were developed a microcontroller-based system devoted to the newborn incubator, in order to check the conditions of the environment provided to the premature newborns, a control system of humidity and software that carries out the reading of the sensors. Two microprosecuted, similar newborn incubator were used, for the realization of the measurements, being that one of the newborn incubator used distilled water and other one was valued without water. The measures were collected to each 2 minutes during 96 h. The relative humidity inside of the newborn incubator, without water had average (46.53 ± 3.84) %. The mean value of the internal temperature was of (36.58 ± 1.04) ºC. With water, without control of humidity, (70.67 ± 3.71) %. The mean value of the internal temperature was of (34.33 ± 1.84) ºC. With water and with control of humidity, was inside the established belt of comfort for the standard. One checked that the newborn incubator used in this inquiry does not provide to the premature newborns a totally appropriate environment taking into account the requisites of the standard NBR IEC 601-2-19.
