Proximity sensor detects the presence of nearby objects without any physical contact using infrared sensor. The infrared sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target.
The operating distance of the sensor depends on the actuator's shape and size and is strictly linked to the nature of the material.

CHAPTER ONE
1.0                                                        INTRODUCTION
Proximity Detection Sensors detect and measure reflected infrared (IR) energy to detect the presence of an object or person.  The proximity detection devices offer a wide range of performance, with LED drive currents and IR pulse repetitions. The proximity detection circuitry compensates for ambient light, allowing it to operate in environments ranging from bright sunlight to dark rooms. The wide dynamic range allows operation in short-distance detection applications behind dark glass, such as cell phones. Proximity Detection Sensors can be used for a mechanical switch replacement or to sense human gesturing.
Proximity sensorsdetect the presence or absence of an object. Examples of proximity sensor usage include detecting an out-of-paper condition in a printer or a mobile phone screen that dims to save battery life when placed near a face.
Proximity sensors can be used in industrial, automotive and consumer applications.

1. OBJECTIVE OF THE PROJECT

The objective of this work is to build a device which can be used to detect the presence of nearby objects without any physical contact. It does this by emitting an electromagnetic field or a beam of electromagnetic radiation (infrared) and looks for changes in the field or return signal.

1. SIGNIFICANCE OF THE PROJECT

As a student of electrical/electronic engineering, this work has exposed me to know the application and description of many electronics components. It also made me to know that an object can be detected by electromagnetic field without making any physical contact with the object.

1. APPLICATIONS OF THE PROJECT
1. Parking sensors, systems mounted on car bumpers that sense distance to nearby cars for parking
2. Ground proximity warning system for aviation safety
3. Vibration measurements of rotating shafts in machinery
4. Top dead centre (TDC)/camshaft sensor in reciprocating engines.
5. Sheet breaks sensing in paper machine.
6. Anti-aircraft warfare
7. Roller coasters
8. Conveyor systems
9. Beverage and food can making lines[3]
10. Mobile devices
11. Touch screens that come in close proximity to the face
12. Attenuating radio power in close proximity to the body, in order to reduce radiation exposure.

   1.4                                              SCOPE OF THE PROJECT
The project is designed to measure the proximity of any object by using an infrared. Infrared means of proximity measurement is a convenient method compared to traditional one using measurement scales.
An object moving nearby actually reflects the infrared rays emitted by the infrared LED. The infrared receiver has sensitivity angle (lobe) of 0-60 degrees, hence when the reflected IR ray is sensed, the mono in the receiver part is triggered.

1.6                                          ADVANTAGES OF THE PROJECT

1. Good stability
2. High Speed
3. infrared sensors are good in terms of power
4. Usage Low cost.

1.7                                                        METHODOLOGY
To achieve the aim and objectives of this work, the following are the steps involved:

1. Study of the previous work on the project so as to improve it efficiency.
2. Draw a block diagram.
3. Test for continuity of components and devices,
4. Design of the device was carried out.
5. Studying of various component used in circuit.
6. Construction of the circuit was carried out. The construction of this project includes the placing of components on Vero boards, soldering and connection of components,
7. Finally, the whole device was cased and final test was carried out.

1.8                                        PROJECT WORK ORGANISATION
