Solution: Develop a Data Aggregation System

Explore how to design abstract sensor interfaces and adapter classes to integrate diverse devices. Learn to implement a data aggregation system that compiles sensor readings efficiently, enhancing your skills in advanced Python design patterns.

We'll cover the following...

Create device interfaces

Define abstract classes TemperatureSensor, HumiditySensor, and MotionSensor, outlining common interfaces for sensors with methods to retrieve temperature, humidity, and motion detection status.

Python 3.10.4
from abc import ABC, abstractmethod
class TemperatureSensor(ABC):
  @abstractmethod
  def get_temperature(self) -> float:
    pass
class HumiditySensor(ABC):
  @abstractmethod
  def get_humidity(self) -> float:
    pass
class MotionSensor(ABC):
  @abstractmethod
  def is_motion_detected(self) -> bool:
    pass

Code explanation

  • Line 3–6: Created the TemperatureSensor abstract base class with the abstract method get_temperature() for retrieving temperature as a floating-point value.

  • Line 8–11: Created the HumiditySensor abstract base class featuring the abstract method ...
