- 9. Bluetooth Module HC-05 For the communication between mobile phone and microcontroller Bluetooth module(HC-05) is used. HC-05 is low power 1.8V operation and is easy to use with Bluetooth SPP (serial port protocol). Serial port Bluetooth module have a Bluetooth 2.0+EDR (enhanced data rate), 3Mbps modulation with complete 2.4GHZ radio transceiver and baseband. 27-07-2021 9
- 10. Relay Relay isbasically an electromagnetic switch which can be turn on and off by an applying the voltage across its contacts. In this project we used a 5V 2-channel relay. 27-07-2021 10

- 14. Software Used forBluetooth Control The Android platform includes support for the Bluetooth network stack, which allows a device to wirelessly exchange data with other Bluetooth devices. The application framework provides access to the Bluetooth functionality through the Android Bluetooth APIs. Control home electrical system using smart phone with android application and Blue Switch Module. Blue Switch Module’s outputs to directly drive loads like bulbs, Lamps, Sockets, Television, Fans etc. For download and installation many apps are available on Google Playstore. 27-07-2021 14

- 18. Advantages It isa robust and easy to use system. There is no need for extra training of that person who is using it. All the control would be in your hands by using this home automation system. This project can provide the facility of monitoring all the appliances with in the communication range through Bluetooth. The schematic of Arduino is open source, for the future enhancement of the project board can be extended to add more hardware features 27-07-2021 18
