Home automation is building automation for a home, called a smart home or smart house. A home automation system will monitor and/or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems. When connected with the Internet, home devices are an important constituent of the Internet of Things.Project AIM : Smart Module can control Home electronics Appliances using Smart phone, Touch Control, IR remote and voice assistant like Alexa and Google.
By using CYPRESS chip able to achieve project aim.
Pilot project design
Touch Input
Voice Input
For the demo purpose we are starting with 4 light controls and 1 fan control. Below diagram is the schematic diagram of the power module.
