This paper presents a new mechanism exploiting the redundancy of sensors to ensure reliability in measuring baby incubator parameters where no error is tolerated. Several research based on the sensors redundancy have been done to several various areas, e.g., aerospace, automotive. However, no investigation is done, based on this technique, to ensure reliable measurement of baby incubator parameters. This paper, precisely, addresses this luck by proposing a new mechanism to precise and efficient measurement of temperature in an incubator. Our way of using redundancy consists in the use of a double of materials sensors with an analytical sensor as well as a time-redundant. Our new solution has been validated through several tests on baby incubator. Our tests showed that our solution enables the reduction of transitory events and faults in sensors.
