• actuator

• sensor

• controller

• process

a device that can trigger mechanical action based on input from a controller

• actuator

• sensor

• controller

• process

What types are these related to electrical, hydraulic, pneumatic

• actuator

• sensor

• controller

• process

a simple microcontroller that can be used in IoT projects

• actuator

• sensor

• arduino

• raspberry pi

a series of steps or actions taken to achieve the desired result

• process

• sensor

• plant

• raspberry pi

a type of feedback loop that contributes to, or reinforces, the original input

• Negative

• Positive

the part of a control system that is controlled and that changes the output of the system

• plant

• controller

• input

• sensor

a control system that does not use feedback

• open-loop

• close-loop

physical communication media that is easy to install and reliable but is susceptible to signal degradation because of distance limitations and interference

• fibre-optic

• plastic

• copper cable

• aluminum cable

The medium is essentially the air, which transmits radio and microwave frequency signals.

• wired

• wireless

• copper

• fibre-optic
