Wireless Home Automation System by Using HM2007 Voice Recognition Device


This paper introduced design and implementation of wireless home automation system (WHAM), which is developed using an Arduino microcontroller, Bluetooth wireless communication technology, and voice recognition based on HM2007. Software Development Kit HM2007 is embedded system to detect and recognize human voice commands and it converts into binary format and send respective digital representations to the microcontroller. The microcontroller then interprets these data signals, compares them with a database and thus identifies the referred load and its desired state. A Bluetooth module was added to microcontroller, so as to control lights and electrical appliances in the home. This system is most suitable for the elderly and the disabled persons, especially those who live alone and since recognize voice so it is secure. The response time is 1.2 sec which is efficient in these applications
