CFBEDEAK
When an actuator's effect changes the next sensor reading, so the system keeps adjusting itself until the stored value is reached, e.g. a heater warms the room until the target.
2
MTEAADUTO NILGTGHI
Lights switched on, off or dimmed by sensors and a microprocessor with no one touching a switch, e.g. a street lamp that comes on when its light sensor detects dusk.
3
ORSKW OYCOULNNTIUS
An automated system runs 24 hours a day with no tiredness or breaks, so it can monitor and control a process all the time and react quickly to every sensor reading.

1CFBEDEAK → feedback — When an actuator's effect changes the next sensor reading, so the system keeps adjusting itself until the stored value is reached, e.g. a heater warms the room until the target.
2MTEAADUTO NILGTGHI → automated lighting — Lights switched on, off or dimmed by sensors and a microprocessor with no one touching a switch, e.g. a street lamp that comes on when its light sensor detects dusk.
3ORSKW OYCOULNNTIUS → works continuously — An automated system runs 24 hours a day with no tiredness or breaks, so it can monitor and control a process all the time and react quickly to every sensor reading.
