Abstract

Integrated Home Security System (IHSS) is a system that is bui lt to acknowledge the authorized party by using a telephone call if the house is entered without permission. This proj ect will concentrate on Designing User Device and Sensor Circuit for IHSS which is called as Part I of the IHSS. This part has three important circuits that are the remote controller circuit, the receiver circuit, and the sensor circuit. There are two possible conditions for the sensor circuit which are idle condition and active condition. If there is a di sruption from the door, the sensor circuit will be activated and a signal will be transmitted to the Auto Dialer. The Auto Dialer will be discussed in Part II . The magnetic sensor will be used in this project as the device that will detect the act ion from the door. This magnetic sensor is very cheap and suitable for this project. The funct ion ofthe remote controller is to control the system and to set the condition of the system. In this project, two LEOs were used to indicate condition of the system. The red one was used to indicate idle condition while the green one to indicate active condition.
