The purpose of this experiment is to demonstrate how this little product reacts to motion. The Motion Detector also known as the GHANTA detector is a type of electronic device that contains an electronic sensor that detects motion that can be either integrated in it or also can be connected to other external devices that agile the user of the existence of a moving object within the field of view. They play a very important role in the field of security, for both homes and businesses. The Motion Detector contains a motion sensor that transforms the detection of motion into an electric signal. And so which is used by us, to make our lives easier. So the purpose of this experiment is to see whether it complies with the terms of Security & whether it is really useful in terms of security. IV. Introduction: Background: The detection of motion finds its origin in the field of astronomy, which dates from thousands of years ago. Early farmers looked on to the skies and utilized the movement of stars to determine when to plant their crops and when to harvest them. The first motion detection system radar was initiated by Heinrich Hertz. Hertz studied the properties of waves and found out that waves could bounce off of objects and had different speeds. These motion detectors were also used in World War II, They were already so advance, that the military could detect advance attacks against them, and so could prepare & protect themselves from these attacks. Significance of the Study: The significance of this product is to detect & prevent us humans from serious accidents. An example of a use is with industrial equipment, there are new motion detectors that can detect when a person's arm gets too close to machinery, and alarm to warn the person. There are also motion detectors, usually used in supermarkets, wherein the door automatically opens as it senses a human or an object in front of it. General & Specific Objectives: The General target or objective of this project is to detect motion and light the bulb when it detects motion. The Specific objectives are the purpose of the experiments, the first experiment was to determine the correctness of position of parts. The second experiment was to determine the proper placement of the wirings. The third experiment was to determine the functionality of the project. The fourth experiment was to determine the main purpose, meaning the correct detection of the project. Scope & Limitations: One thing that confuses PIR sensors, is a brick wall that is hit by the sun during some part of the day. The brick wall, becomes very hot, obviously because of the heat of the sun, and even a human moving in front of it is not detected much rather than the heat of the wall, so it reacts to a lot of things and not only humans. Another limitation of these devices is that depending on the background they may take a little time to detect motion. In this, common devices take a couple of seconds to be sensed by the detector. Related Literature: Breadboard: A breadboard is known as a construction base for a prototypes. In modern times such as today the term is commonly used to refer to a particular type of breadboard known as the solderless breadboard, this is used commonly in experiments, & this required no soldering, so you don’t destroy the parts & you can reuse them again & also correct your connections easily. Operational Amplifiers (OP AMP): An operational amplifier also known as the OP AMP is a DC-coupled high-gain electronic voltage amplifier which has a differential input and, usually, a single-ended output. An operational amplifier gives off an output voltage that is typically hundreds of thousands of times larger than the voltage change between its input terminals. CDS Cells: A photoresistor also known as a light dependent resistor (LDR) or cadmium sulfide (CdS) cell is a resistor whose resistance decreases with increasing incident of light intensity, so more light intensity means lesser resistance. It can also be accredited to as a photoconductor. Pentiometer: A potentiometer (commonly known as a quot;
potquot;
) is a three-terminal resistor meaning with three terminals which has a sliding contact that courses an adjustable voltage divider. If only two terminals are used (one side and the wiper), it represents a variable resistor. Potentiometers are commonly used to control electrical devices common in audio equipment such as amplifiers and amplified speakers for volume & other audio controls. Potentiometers operated by a mechanism that can be used as position transducers, such as, in a joystick. Definition of relevant terms: ,[object Object]
