The article aims to present a prototype device able to identify and warn those responsible when there is a possibility of forgetting of a child inside the car, thus avoiding an injury to the health of the child or even death. To this effect electronic sensors able to detecting the presence of the child on the chair have been used, microcontrollers (Arduino Uno, Arduino Nano) programmed to perform the data processing, wireless communication module (XBee) to perform the transfer of data between the chair, and a specific key chain, and ultimately actuators responsible for a possible warning against forgetting a child inside the car. Generally speaking, this article comprises concepts involving instrumentation and programming. This paper has the effect of academic results, nowadays there are not many studies concerning the proposed theme and its application is highly viable because of the relatively low cost, making it accessible to all social classes.
