A **parking meter** is a machine located next to limited parking areas. Its function is to regulate the time a vehicle can be parked in a specific place. Drivers must pay a fee to obtain a ticket that allows them to park for a determined period. This machine is common in areas where parking is controlled to ensure vehicle turnover and prevent a single vehicle from occupying a space for too long.

The **breathalyzer** and the **parking controller** are not related to limited parking. The breathalyzer is a device used to measure the blood alcohol level of a driver, while the term "parking controller" does not refer to a specific machine, but rather to a person or system that supervises compliance with parking regulations. Therefore, the correct answer is the **parking meter**.
