AbstractBaby Near is the project created to assist parents to monitor their children in open or closed environments, mainly with crowds, such as supermarkets, malls, playgrounds, among others. The prototype consists of two ends that communicate with each other by Bluetooth, one with a smartphone and another with an Arduino. If the distance between them is highier than the one set by the parents, the cellphone device emits sounds, vibrations and changes on screen that alert the parent that the distance has been exceeded. In addition, the end of the Arduino also has a short distance electronic tag that can be used by parents to insert information relevant to the child's finder. In this way, the system brings to the parents more speed in the detection of an emergency situation due to the increase of the distance of the child.
