[LASER BASED SECURITY ALARM SYSTEM] This Document contains Project Report of Autumn 2012 of Course CT-111. PROJECT REPORT LASER BASED SECURITY ALARM An Alarm is a type of security equipment that can be used to safeguard houses and property. Now a days Burglar Crimes are continually rising with each passing day. Many have lost homes and families through violent burglaries in many countries Some of them lost most precious things such as Jewelry‚ Vehicles‚ huge investments in banks etc..
Premium Amplifier Output Input
circuit based on a latch whose output changes when its CLOCK input receives a pulse. Frequency The number of cycles per unit time of a periodic waveform. Hertz (Hz) Unit of frequency. One hertz equals one cycle per second. Integrated Circuit (IC) An electronic circuit having many components‚ such as transistors‚ diodes‚ resistors‚ and capacitors‚ in a single package. Inverter Also called a NOT gate or an inverting buffer. A logic gate that changes its input logic level to the opposite state

Gas leak detection is the process of identifying potentially hazardous gas leaks by means of various sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor‚ Ultrasonic gas detectors‚ electrochemical gas detectors‚ and Semiconductor Sensors. More recently‚ infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications‚ and can be found in industrial
