Home Automation

● Control Thingsa. Gates, lamps, shades, music..

● Monitor Thingsa. temperature, humidity, presence

● We need controllers...

Home Automation

● Small Computer = Microcomputer○ Low energy consumption○ Limited Resources○ Do somethings at the same time

● Very small computer = Microcontroller○ Very low energy consumption○ Very Limited Resources○ Do a few things at the same time

Today

● Control home any appliance using:

○ Arduino: very small computer

○ Concept Board: small computer + cell phone

○ Raspberry Pi: medium size computer

Basic Control: on / off

● Turn on / off home appliance is a nice start!

● We can use a relay to turn on / off energy;

● We need to control this relay!
