Abstract: The "Child Tracking System" represents a progressive and impactful endeavor to address the paramount concern of child safety during emergency situations. This innovative project harnesses the capabilities of the Internet of Things (IoT) by integrating key components such as the NodeMCU, GPS module, and a panic button. In a world where ensuring the well-being of children is of utmost importance, this system emerges as a technological safeguard designed to provide real-time tracking and immediate response capabilities.At its core, the NodeMCU serves as the technological linchpin, facilitating seamless connectivity to the internet. Through integration with an IoT platform like ThingSpeak or Blynk, it establishes a dynamic communication channel essential for robust data exchange. Complementing this connectivity is the GPS module, a critical component responsible for furnishing accurate and timely location data. By leveraging GPS technology, the system ensures precise tracking of a child's movements, delivering a heightened level of security.

Keywords: NodeMCU, GPS module, Blynk, Security.
