This paper presents an intelligent temperature control design with smart protection techniques, implemented in newborn incubators. The operation of the temperature control was focused on the use of a programmed microcontroller, which respond with pulse width modulation at the heater, and thus achieve, high precision temperature regulation. The novelty of this design, lies, on the protection technique used. That is based, on a constant monitoring of the incubator thermal variations; at several parts of the environment. That allows establishing, an approach for the shutdown of the heater and the alarm on, depending on the individual reading of 4 sensors NTC thermistor, strategically located within the incubator. This design is motivated by the necessity of adapt modern controls to old incubators that can be fully recovered; also opens the possibility to design a complete new incubator. It is important to note that this project contributes with our own development technology; especially on biomedical engineering, instrumentation and control.
