All of these devices can be easily controlled by a single controller, using the personal area network in a home environment. Busy environment and personal limitation the market goes towards home automation and networking and Bluetooth is an ideal solution for this purpose. In buildings, temperature and other electronic devices can be easily controlled by home automation, but the high degree of computer work is involved. This report shows a simple home automation system consisting of remote mobile, host controller, and various home appliances. The client module can communicate with the host controller through a wireless device such as Bluetooth.
Automation is also involved in the building management system in which lights, temperature, safety devices and other devices are controlled through a high degree of computer involvement. In this report, all devices used in the building management system are controlled by a single controller that uses a wireless network. The client module and the host controller are used to communicate with each other through a wireless device such as Bluetooth enabled for the mobile phone. In this report, an Android-based smartphone is used. Home automation is not new, but the advanced automation system today requires a large and expensive infrastructure. In this report, we have proposed a low-cost, flexible automation system that can easily control TV, tube lights and fans of Android-based mobile phone via Bluetooth. Here you use the HC-05 Bluetooth module and the 8-bit microcontroller atmel89s52 to switch. This board has 32 digital input and output ports.
