This project work deals on the design and construction of an IR based remote control for an electronic/electrical device say electric lamp with the aim of switching on/off of the lamp at discretion and from a distance. It also eliminates the inconveniences associated with manual switching of bed lamps. This electronic system is designed in two functional units; the transmitter and the receiver using IR communication wave band. The tr […]
This device is a security device that indicates when an intruder or object passes or cut the light infrared. The system will clearly warn immediately, command give an indication through 7-segment display. Circuit diagram of this device uses an infrared sensor to sense intrusions. Infra red rays reflected from a static object will be in one phase, and the rays reflected from a moving object will be in another phase. The circuit uses th […]
This work is design and construction of an Infrared (IR) based transmitter and receiver, which is a wireless communication technology. Infrared (IR) communication is used in remote controls of different appliances like TV’s. The handheld remote control of the TV consists of IR Transmitter and the IR Receiver is placed at the TV. An infrared transmitter and receiver consist of IR Transmitter and Receiver Modules. In this project, we bui […]
The project is on an infrared based fence protecting alarm system used in places like homes, shopping malls, hotels and theatres for detecting movement of a human being close to the fence or an intruder attempting to burglarize an environment via the fence. This project proposes a system of automatic sensing any body movement object near the fence. This is achieved with help of a PIR (Passive Infrared) sensor which detect an infrared […]
