  1. Project Title PRE-STAMPEDE MONITERING AND ALARM SYSTEM Under the Guidance of Submitted by

  2. ABSTRACT This project will help us develop a pedestrian flow prediction and risk management system in most of pilgrimage places, in buses and may apply to many other shopping districts. In this project development process, number of push button are set, depending upon the number of switches pressed by the pedestrians will give an signal to a programmable microcontroller of 8051 family conducts the transistor and in turn buzzer sounds indicating the pedestrians are crowded. The status is displayed on the LCD.

  10. LEDS LEDs are semiconductor devices are made out of silicon,When current passes through the LED, it emits photons as a byproduct. Normal light bulbs produce light by heating a metal filament until its white hot LEDs present many advantages over traditional light sources including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching

  11. BUZZER • Piezo Buzzer • This buzzer is an piezo type audio signaling device, which has a piezo • element and a oscillating circuit inside which oscillates the piezo brass base • plate, which when given voltage difference produces sound of a predefined • frequency. • Features • These high reliability piezo buzzers are applicable to general electronics equipment. • Compact, pin terminal type Piezo buzzer with 4 KHz output. • Pin type terminal construction enables direct mounting onto printed circuit boards.

  12. BC547 • The BC547 transistor is an NPN Epitaxial Silicon Transistor. • The BC547 transistor is a general-purpose transistor in small plastic packages. • It is used in general-purpose switching and amplification BC847/BC547 series 45 V, 100 mA NPN general-purpose transistors. • Whenever base is high, then current starts flowing through base and emitter and after that only current will pass from collector to emitter
