The aim of this project is to provide security in shopping malls and save the power upto the maximum extent. This project uses wireless communication, IR. The appliances like lights, motors, power controlling system etc can be controlled in this project. We can control all loads at a time from one place (control room) without connecting any physical wire between loads and control room.
This Project describes a design of effective security alarm system that
can monitor the shopping malls with eight different sensors.
Unauthorized
access, Fire accident, wall braking, IR detection and fire detection can be
monitored by the status of each individual sensor and is indicated with an LED.
This security system works perfectly all the time i.e., whether some one is
present in the industry or not.
IR remote acts as the
transmitter in this project. When a button is pressed in the remote, the signal
will be passed and received by the IR receiver TSOP Receiver. This signal is
sent to the microcontroller which decodes the signal and performs the
corresponding action in accordance with the button pressed in the remote. This
remote can be used to operate the appliances or also to provide security.
When anything goes
wrong in the shopping mall, this signal will be immediately detected by the
microcontroller, buzzer indication will be given and all the doors can be
closed instantaneously. Then the checking process can be started.
