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 […]
ABSTRACT Automatic street light control system is used in modern world for energy savings by using Light dependent Resistor (LDR). Nowadays the human has not enough time, and he/she is unable to find time even to switch the lights on or off. This new system can be used more effectively in case of street lights. In proposed system, the street lights will be switched on just before the sun sets and are switched off the next day morning […]
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 […]
