摘要：In remote home monitoring security system, embedded devices play a vital role. In this study, GSM, ARM and ZigBee are used to establish a security for smart home. In this study, LPC2148 is used as Microcontroller Unit (MCU), Resistance Temperature Detectors (RTD) to observe temperature, smoke sensor to detect the presence of smoke and vibration sensor over doors and windows to detect forced entry, overall system safeguard the home from burglary. On entering the correct password, MCU disarms the security feature else it activates the alarms and sends image of the burglar to amenable persons through ZigBee and whenever there is smoke or fire MCU sends SMS to owner as well it automatically activates safety measures like, opening window turns on the exhaust fan and sprinkler.
