The Internet of Things has emerged as one of the key aspects for the future of Wireless Sensor Networks. Wi-Fi is one of the main wireless communication protocol for connecting different devices for exchange of data over Internet. IoT is implemented in smart home security to device embedded module for standalone operation of collecting and monitoring different sensor data for home security. This paper discusses about implementation of raspberry pi based Automatic service request system for smart home security associated with web server or cloud via Internet using the wireless network. The Proposed system would be based on cloud storage. This system was used for monitoring the status of home by using different sensors. The sensor data is processed by raspberry pi and if any abnormality found then it will automatically send service request to the concerned person regarding the abnormality.
