Abstract:Child safety has become a major societal concern in crowded public environments where young children are vulnerable to separation from caregivers. Children between the ages of three and seven are particularly susceptible due to their curiosity and limited awareness of potential dangers. This research proposes a compact and cost-effective anti-abduction device designed to alert caregivers when a child moves beyond a predefined safe distance.The proposed system utilizes wireless communication to establish a connection between a child module and a parent module. Several communication technologies including WiFi, Bluetooth, GPS, and LoRa were analysed to determine their suitability for short-range monitoring. Based on factors such as cost, power consumption, and signal stability, the ESP32 microcontroller with WiFi connectivity was selected as the core component of thesystem.
