2 Smart home control system architecture
2.2 Sensors and actuators

The sensors are basically the eyes and ears of the home network. There are various sensors:

  • temperature measurement
  • measurement of light intensity or UV radiation
  • level measurement of liquid or its presence
  • gas detection
  • movement detection
  • noise detection

Actuators are enforcement of actions. Depending on the type of required interaction can be divided into mechanical (pump), electrical (motor) or electronic (dimmer, relay).
