Multisensors System for Real Time Detection of Length, Weight, and Heartbeat of Premature Baby in The Incubator

Premature babies inserted into the incubator will always be monitored progressively, especially the heart rate, body length, and body weight. The aims of this research are to design and to create an incubator that can detect the abnormalities of baby's heartbeat through the baby's fingers in continuous and real time by using pulse sensor. The incubator also able to measured baby's length and weight automatically by using ultrasonic sensor and load-cell sensor, respectively. The output of all sensors will be processed and calibrated by Arduino Microcontroller, then the results will be displayed on the liquid crystal display (LCD). The systems also able to allow some notifications if any abnormalities have been occur. As a result, the heartbeat detector has a precision of ±95% when compared to a reference heartbeat detector. The system also can measure the length and weight of the infant with the measurement results are closer to the reference instrument, which the average error is not more than 5%. The results are most likely is a good preliminary results in order to build a smart incubator.
