Using modern technology, the Contactless IoT Doorbell & Security System is intended to improve convenience and home security. A Raspberry Pi serves as the central control unit and is the brains of the system. This little computer handles activities related to communication and control while processing data from several sensors.

You can watch in real time who is at your doorstep thanks to the Camera Module, which records live footage of anyone approaching the door. The Ultrasonic Sensor allows the system to identify a person’s presence without making physical contact with them by measuring their distance from the door.

The Speaker plays announcements or noises, like a doorbell chime or a welcome message, for notifications and communication. Visual information, such as system status or notifications, is provided by the LCD display.

By using a Wi-Fi Module to connect to your home network, the system allows for remote access and notifications. This allows you to monitor the camera feed and get alerts on your computer or smartphone. In many circuits, resistors, capacitors, and transistors are utilized to control electrical signals and guarantee steady operation. Switches and buttons provide manual system control, including setting parameters and performing resets. Electrical and wirings make sure that every part is energized and linked correctly. The circuit is arranged and secured using a PCB board, and reverse voltage is prevented using diodes. Connectors make it simple and safe to connect various system components. Ultimately, the hardware components are assembled and mounted firmly using screws and fittings.

All things considered, this system combines these elements to produce a smart, contactless doorbell and security system that provides ease and improved home safety.
