In order to reduce the risks of death rates, neglecting by the observers, and sometimes the little number of the medical staff in hospital, A monitoring system based microcontroller in neonatal incubator was developed in this article. An interfacing process is made between the infant, infant incubator, and the computer, by taking the temperature readings and send the results to doctor's or the person who in- charge's phone through Short Messages Service, and to a personal computer PC, with sound alarm on the incubator, every given period of time; A temperature sensor is interfaced with a configured single inline module SIM of phone, the temperature reading that obtained from interfacing method is combined with the readings of the incubator sensor, then the final result will be taken from the microcontroller because it will be more accurate than the incubator’s thermometer.
This system was designed only to check and give an alarm if there was any unaccepted change in temperature due to the normal temperature ranges.
