Executive Summary

Home embedded surveillance system are designed with group of sensors and Micro Controller Unit (MCU). This design consists of two group of sensors, outdoor and indoor. Pyroelectric InfraRed sensors (PIR) and pressure sensors as the alert group in windows and doors where an intruder must pass through. These outdoor sensors wake up the MCU (Micro Controller Unit) which has power management for the ultrasonic sensors and PIR sensors indoors. This state transition method saves a large number of sensors required for the alert power. Majority Voting Mechanism (MVM) are also used to manage the sensor groups to enhance the probability of multiple sensors sensing.
