Abstract
In the last few years there have been incidents where child was killed after being left alone in a car unintentionally for several hours. It is necessary to build
relevant notification systems to address the safety issues of children riding in cars, especially in situations where drivers can be inattentive or ignorant to potential hazards. This project focuses on the development of a Smart Child Trap Hazard Notification System designed to alert drivers if they unintentionally leave their child in the car. The system integrates various sensors and communication technologies, including Infrared (IR) Break Beam Sensors, a DHT22 temperature sensor, and a passive buzzer, all controlled by a NodeMCU Lua V3 ESP8266 WiFi module. These sensors are strategically placed to detect the presence of children in the vehicle and monitor environmental conditions. The system operates in three modes: idle, active, and low power, ensuring efficient use of power while maintaining reliable detection capabilities. When a child is detected in the car while the driver is absent, the system activates the buzzer and sends an alert notification to the driver's smartphone via the Blynk app. The Smart Child Trap Hazard Notification System has demonstrated reliability and accuracy in preventing incidents of children being left in vehicles. By providing real-time alerts to drivers, this system significantly enhances child safety standards, promotes responsible driving practices, and reduces the likelihood of tragic outcomes.
