The objective of this project is to create a security system that automatically takes photos when a door is opened using sonar sensors. The system is built using an Arduino kit and a sonar sensor, and it is designed to be simple, reliable, and easy to use.The project involves several steps. The first step is to choose a sonar sensor that is compatible with the Arduino board. Once the sonar sensor is selected, it is connected to the Arduino board and programmed to detect changes in distance when the door is opened. The sensor will send out a sound wave that will bounce off the door and return to the sensor. By measuring the time it takes for the sound wave to travel to the door and back, the distance between the sensor and the door can be calculated.When the door is opened and the distance measured by the sonar sensor changes, the Arduino board will trigger the camera module to take a photo. The camera module is connected to the Arduino board and programmed to take photos when activated.The system can be customized to include additional features such as an alarm or notifications when the door is opened. For example, a piezoelectric buzzer can be added to the circuit to create an audible alarm, or an Ethernet or Wi-Fi module can be used to send notifications to a phone or email.Overall, this project demonstrates the use of an Arduino kit and sonar sensor to create a simple and effective security system that can be used to monitor doors and windows. The system is designed to be expandable and customizable, allowing users to add additional features and functionality as needed.
