This document summarizes a research paper that designed and implemented a smart home alarm system using Zigbee wireless technology. The system uses an Arduino microcontroller as the central controller connected to various sensor nodes to monitor temperature, gas levels, and security using an infrared sensor. The sensor data is transmitted wirelessly between the nodes and controller using XBee Zigbee modules. The system provides remote monitoring capabilities and was tested to work effectively with a simple and achievable design that could be used to monitor and control smart home devices.
