This Project describes a design of effective security alarm system that can monitor an industry with different sensors. Unauthorized access, Temperature increment, IR detection can be monitored by the status of each individual sensor. Obviously, this burglar alarm also has an input to 'arm' the alarm, a tamper input and a couple of outputs to control a siren and Auto dialing system.
Often times, crime happens when no one is around to notice and the crooks are long gone by the time anyone gets back. Now, you can protect your home or office with the AUTO DIALER SECURITY and SAFETY ALARM. This auto dialer is a step
The Auto Dialer is a unique passive infrared system that monitors motion in an area you select. When the unit is ARMED, the motion detector watches the protected area. Once movement is detected, a 105db security alarm will sound and the Auto Dialer will call up to 5 preset telephone numbers selected by you. You will hear the message and know that your alarm has been tripped.
You can call the police to let them know what's going on and to check out your house.


The uniqueness of this project is not only alerting the neighbors by siren, it also dials a mobile number which is already programmed into the system. A mobile number or a land line number can be programmed into the system. As this system works on existing telephone line, it can dial the number even the subscriber is out of station
