Aim of the Experiment

The objective of this experiment is to interface a DHT11 sensor with a Raspberry Pi and develop a Python program to read and display real-time temperature and humidity data. This experiment highlights the process of sensor integration with the Raspberry Pi using its GPIO (General-Purpose Input/Output) pins, demonstrating how embedded systems can interact with the physical environment.

The integration of the DHT11 sensor with a Raspberry Pi has numerous real-world applications, including:

1. Weather Monitoring Systems

• Collects temperature and humidity data to create a local weather station.
• Can be combined with cloud storage to log data over time for trend analysis.

2. Smart Agriculture

• Monitors temperature and humidity in greenhouses to optimize crop growth.
• Helps automate irrigation systems by integrating with soil moisture sensors.

3. Home Automation & Smart Homes

• Controls HVAC (Heating, Ventilation, and Air Conditioning) systems based on room temperature.
• Sends alerts to smartphones or IoT dashboards when humidity levels exceed thresholds.
