Description

This research focuses on detection of an authorized access to residential and commercial buildings when residents are away fromthe access gate of thehouse .The system is simple reliable and touch less activator security system and uses sensor technology to revolutionized the standard of living .The system provides the best resolution to most of the problems forced by house owners in their daily life. Due to its simple electronic component nature, it is more adaptable and cost effective .the system is divided into three units which employs both the use of the dc battery and the mains supply to ensure constant power supply to the circuit. The design of the system was achieved by considering some factors such as economy, availability of the components and research materials, efficiency, compatability and portability and also durability in the design process. The system works on the principal of thetouch lesssensor. The general performance of the system depends on the presence of intruder enterrring through the door .the overall system was constructed and tested and wok perfectly. The IR theft alarm consists of infrared IR Transmitter, IR receiver and comparator IC LM358. This detector circuit can be used to detect any human entry, obstacles, theft, etc, in order to use IR detector circuit to sense human entry, the IR sensor has to be placed opposite to each other .IR rays is directly falls on IR receiver which in turn is given as input to the ic LM358 which is used as a comparator. Comparator is a circuit which compares two voltages. (Reference voltage and input voltage) produced output according to the input. The output of the comparator is given to the transistor which acts as an inverter and drives a LED and a Buzzer. Buzzer will give you sound if LED is turned ON.

DIGITAL VISTOR COUNTER USING SEVEN SEGMENT AND LDR- electrical trade project
ABSTRACT Digital visitor counter is necessary to count how many people entered into a specific area or how many items are generated in a firm. It helps in counting of people in an auditorium or hall for seminar to avoid congestion. It is a simple electronic circuit which is totally based on the analogue and digital circuit. This is because it has some part of analogue and digital part(7 segment display) in analogue the main part is LDR(Light Dependent Resistor). How does digital visitor counter works It can simply be done by light reference and light sensor are used to detect the person and display the count using 7 segment display with the help of 4026 IC. The light reference and light senor are placed in such a way that the visitor will cross the light path when he/she enters the hall.

DESIGN OF A SENSOR BASED DETECTOR AND MONITORING SYSTEM - electrical diploma trade project
ABSTRACT With improvement in technology and miniaturization of sensors, there have been attempts to utilize the new technology in various areas to improve the quality of human life. One main area of research that has seen adoption of the technology is the healthcare sector. The people in need of healthcare services find it very expensive this is particularly true in developing countries. With improvement in technology previously expensive hospital equipment have been redesigned using current technology. The developments have seen a trend known as Remote healthcare or previously known as Telemedicine As a result, this project was an attempt to solve a healthcare problem facing the society. The main objective of the project was to design a remote healthcare system. It was comprised of three main parts. The first part being detection of a fall, second being detection of Electrocardiogram commonly referred to as ECG or EKG(heartbeat detection) and the last part was providing the detected data for remote viewing. Remote viewing of the data enables a doctor or health specialist to monitor a patient’s health progress away from hospital premises. Recent technology trend has seen Smart watches, fitness trackers and Smart phones with portable heartbeat detectors. All these are commonly referred to as wearable technology. These devices are modeled around another developing technology trend referred to as Internet of Things (IoT). The devices are linked to Smartphones that process and backup the information on a server. This information is later reviewed to give the health status or progress of the user. As the devices are still new to the consumers the cost is still high especially to those in developing countries. The aim of the project was to come up with a Remote Health Detection System that can be made with locally available sensors with a view of making it affordable if it were to be mass produced.

DESGIN OF SHORT CIRCUIT TESTER- diploma electrical trade project
ABSTRACT A short circuit has been a source of problems to the electrical components experienced by electrical technicians and engineers during the assembling of the evaluable components on the board. I have managed to come up with short circuit tester which will automatically detect and indicate the short circuit available in the assembled board. The main aim of coming with this project is to reduce the loss of life of people when short circuit occurs, maintain the life span of valuable components installed in the board and facilitate easy way of troubleshooting the component effect during the repair damaged equipment. The two NPN transistor BC547 is used in the project design to since the presence of short circuit in the electrical circuit. The designed buzzer will automatically have signaled hence turning on Red LED when there is Short circuit in the circuit under the tester thus creating awareness.
