Proximity-Based Alarm System for Child Safety Near Open Borewells & Drains

Abstract

This work focuses on designing a safety mechanism using proximity sensors and alarm systems to prevent children from falling into uncovered bore wells or open drainage pits. For this, the Arduino board, proximity sensor, and ultrasonic sensors are used to monitor the presence of objects near the bore wells. It detects both humans and animals. The ultrasonic sensor detects the distance from the sensor to the object. The proximity sensor detects object movement within a 1– to 10-foot range and triggers an audible alert to prompt timely action. By using sensor-based technology, this solution tackles a serious and recurring safety issue. It supports real-time hazard detection and gives immediate warnings in public spaces. Then, the servo motor automatically closes the borehole with the temporary lid for a specific period. With the help of WiFi, the monitored details are sent as a message to the authorities. The setup is low-cost, easy to use, and suitable for both rural and urban areas. This method plays a crucial role in enhancing safety near open and hazardous zones.
