Remote monitoring in home automation using low cost microcontroller

This paper presents the implementation of a low cost microcontroller for remote monitoring and controlling the home appliances with home security systems. In today´s world with the advancement of technology, ways are being found to make life more comfortable and safe. The main aim behind remote monitoring is to keep a track of the current status of appliances by locally (LAN) or remotely (Internet) to manage and control home automation system. We have designed such a system by which the system administrator can monitor the status and also send an alert SMS via GSM network automatically, if the conditions get abnormal, to a concerned authorities mobile phone. The concerned authority can control the system through his mobile phone by sending AT Commands to GSM MODEM or by taking the necessary steps in user HTML page (Web server) which is password protected. This system finds a wide application in areas where physical presence is not possible all the time.
