Human Presence Automated Door Bell
A human presence automated doorbell refers to a sophisticated device designed to detect the presence of individuals near a door or entryway and automatically trigger a notification, such as a sound or light signal, to alert occupants of the arrival of visitors or intruders. This innovative technology typically integrates motion sensors, infrared detectors, or advanced computer vision algorithms to accurately identify human movements or proximity, ensuring reliable performance in various environmental conditions. The system’s automated functionality eliminates the need for manual operation, enhancing convenience and security for homeowners or businesses.
This work is human presence activated doorbell system. When someone comes to our house and he searches for the doorbell switch and then rings it to let us know his presence. If the who came to our house cannot find the doorbell or else if the person is so short that he cannot reach the doorbell, what can be done? How will it be if we use an automatic doorbell which rings as soon as a person arrives at our place? There are no more hassles. The person who comes to our house need not search for the doorbell and press it any more. If we install this automatic doorbell using object detection circuit, the circuit will automatically sense the presence of the person and it rings the doorbell.
This circuit operates using a pair of ultrasonic transmitter and receiver modules which are used to detect the person and then if the person is detected, the door bell is automatically turned ON when the person is in-front of the door.

INTRODUCTION
1.2 BACKGROUND OF THE PROJECT
The necessity for some means by which someone on the outside of a door could notify someone on the inside of his presence has been recognized for centuries. The earliest solution to this problem consisted of the simple expedient of knocking on the door with one’s fist. As the human race grew in wisdom and technical sophistication, new and subtler methods were invented. The first of these was the mechanical door knocker, which saved man untold pain from bruised knuckles. Then with the advent of electronics came the electrical door bell, the evolution of which over the past two decades has seen the invention of a number of methods capable of detecting the approach of a person to a door at a distance and triggering the production of an appropriate sound on the inside of the door. Unfortunately, all such methods devised so far suffer from disadvantages which have prevented their widespread application to residential doors.
These methods can be divided into three categories on the basis of the principle used to detect the approaching person. The first category involves the use of a mechanical switch which is activated when the person steps on it. The second involves the use of a photoelectric sensor and a light source arranged so that the person casts a shadow on the sensor as he approaches the door. The third involves some type of capacitance proximity sensor which detects the change in capacitive coupling between a metal sensor plate and ground, or between two plates mounted on or near the door, that results when a person approaches them.
None of the three categories has achieved wide acceptance in residential applications, principally because they are all difficult to install, limiting their usefulness primarily to those instances when they can be built in during the construction of the building.
The mechanical switch method requires that a mat containing many such switches be placed in front of the door in such a way that anyone approaching the door must step on it. Not only are such mats highly unaesthetic, but it must be connected to the sound producing unit inside the house, requiring that a hole be drilled through a wall. This sort of installation is beyond what most homeowners have the time or skill to attempt, and is therefore usually done by professionals, greatly increasing total cost.
The photoelectric method requires that a light source and photodetector be mounted on either side of the path leading to the door. Here again, installation is usually done by professionals, and unless it is possible to hide the units in shrubbery, the light source and detector can be even more unaesthetic than a mat.
Installation of a doorbell based on a capacitance proximity sensor is somewhat simpler than that of a mechanical switch or photoelectric unit in that the entire device can be mounted on the inside of the door. However, in order to obtain even the minimal detection range of two feet, metal sensor plates of several square feet must be used, and while these cannot be seen from the outside they are painfully obvious from the inside.
In order to overcome the disadvantages of the methods discussed, it is clear that the ideal automatic doorbell would consist of a single small battery-operated unit, requiring no electrical connections at all. Installation would consist of driving a nail into the door and hanging the unit from it. The automatic doorbell herein described seeks to meet these criteria.
1.2 PROBLEM STATEMENT
Conventionally, door bell is activated once the visitor approaches the door of the host by making contact / pressing the switch at the door, and this gives the visitor stress when locating the switch most especially at night when everywhere is covered with darkness. However, this device came into existence to overcome the problem of searching for the switch before a door alarm is rung. This device rings an alarm once the visitor approaches the door from a set distance.
1.3 OBJECTIVE OF THE PROJECT
