Abstract – The research entitled security and power saving system using embedded technology is a type of sensing device. This research describes a design of effective security system that can monitor an office, home or industry with PIR sensors. Unauthorized access, temperature increment, IR detection can be monitored by the status of each individual PIR sensor. Crime happens when no one is around to notice. Now this technology can protect user’s home or office with the AUTO SMS SECURITY. The system sends SMS to a particular mobile number when it detects any human motion in that room. This system is also used as a power saving system. While the system is in the power save mode, the sensor automatically monitors any temperature variation (human motion) in office or home. When any human motion is detected in that particular room, the lights and fans which are connected to the system will become ON. When no one is presented at that room, the lights and fans will become OFF state. Embedded systems have the control of the common devices in use today. Embedded system is dedicated to do specific tasks, design engineers can optimize it, reducing the size and cost of the product, or increasing the reliability and performance. The PIR sensor is connected with the PIC microcontroller and it keeps on sensing any human motion and if found any, it sends SMS to a particular mobile number and in power saving mode, it turns on the necessary relay to turn on the respective lights and fans.
