Parents today are concerned about their children and want to keep a constant eye on them. Since this is physically impossible, safety monitoring systems were developed to enable parents to keep an eye on their kids' whereabouts from anywhere in the world. Child monitoring systems can aid parents who need to maintain tabs on their children's whereabouts as well as alleviate the big problem of missing children. The use of geofencing technology enhances the ability to resolve this issue successfully. For determining the child's border, the system makes use of a Node MCU controller. When the child arrives, alert messages are received.
