Abstract

The purpose of this project is to save the power used in places like libraries, staircases, parking, gardens etc. where lots of power is wasted unnecessarily by keeping the fans and lights ON even when there is no one present, and also at places where security is paramount and an alarm needs to be generated when someone is passing by. Thus, using
the same machine, it can be used to save the power and also as a security alarm using a simple sensor called Passive Infrared (PIR) Sensor. When a person enters the monitored area, the Infrar ....etc

Obstacle detection with IR sensor (infrared)
The basic concept of IR (infrared) obstacle detection is to transmit the IR signal in one direction and a signal is received at the IR receiver when IR radiation bounces from a surface of the object.
Here in the figure the object can be anything that has a certain shape and size, the IR LED transmits the IR signal to the object and the signal is reflected back from the surface of the object. The reflected signals are received by an IR receiver. The IR receiver may be a photo-diode / photo-transisto ....etc

pwm based on dc motor control using at89s52 microcontroller

A pulse width modulator (PWM) is a device that may be used as an efficient DC motor speed controller or light dimmer. This project is a versatile device that can control DC devices which draw up to a few amps of current. The circuit may be used in either 12 or 24 Volt systems with only a few minor wiring changes. This device has been used to control the speed of the DC motor and to control brightness of an automotive tail lamp. A PWM circuit works by making a square wave with a variab ....etc
