What function is performed by an actuator?
- measuring a physical property by detecting information from the physical world
- receiving a signal from a device and performing a set action
- collecting data and then sending instructions for actions to be taken, or sending information for further analysis
- improving a physical environment by measuring changes

Measuring a physical property is the function performed by a sensor. Collecting data from sensors and then sending instructions for further actions or sending collected data to another device for further analysis is the function performed by a controller.
