# Smart HVAC System to Provide Optimal Cooling Support to a Building
## Project Overview
This project aims to design and implement a smart HVAC (Heating, Ventilation, and Air Conditioning) system that optimally regulates temperature and humidity within a building. The system integrates Arduino-based automation with various sensors and actuators to enhance energy efficiency and occupant comfort.
## Features
- Automated temperature and humidity control
- Real-time monitoring using an LCD display
- Integration with DHT11 sensor for environmental data collection
- HVAC system response based on predefined setpoints
- Alarm system for extreme temperature or humidity levels
- Energy-efficient operation using Arduino-based automation
## Components Used
- **Arduino UNO** (1 unit)
- **DHT11 Sensor** (1 unit) - Measures temperature and humidity
- **Capacitive Touch Sensor** (1 unit)
- **Breadboard** (1 unit)
- **LEDs** (4 units)
- **Alphanumeric LCD Display** (1 unit)
- **Servo Motor** (1 unit)
- **Jumper Wires** (20 units)
- **Sliding Potentiometer** (2 units)
- **Rotary Potentiometer** (1 unit)
- **Resistors** (4 units)
## System Architecture
The system uses an Arduino UNO microcontroller as the core processing unit. The DHT11 sensor collects temperature and humidity data, which is displayed on an LCD screen. Based on user-set values and predefined thresholds, the HVAC system adjusts cooling levels using actuators. The alarm system triggers a buzzer when extreme environmental conditions are detected.
## Code Implementation
The project is programmed using C++ and the Arduino IDE. The core functionalities include:
- Reading sensor data from the DHT11
- Mapping analog input values from potentiometers to set environmental thresholds
- Controlling LEDs and servo motors based on environmental readings
- Triggering an alarm if conditions exceed safe limits
## How to Use
1. **Setup the hardware**: Connect all components as per the circuit diagram.
2. **Upload the code**: Use Arduino IDE to upload the provided source code.
3. **Monitor environmental parameters**: The LCD display will show real-time temperature and humidity readings.
4. **Adjust setpoints**: Use the potentiometers to modify temperature and humidity setpoints.
5. **Observe HVAC response**: The system will automatically regulate cooling and trigger alarms as needed.
## Future Enhancements
- Integration with IoT for remote monitoring and control
- Use of more advanced sensors for improved accuracy
- Implementation of AI-driven predictive cooling models
- Integration with renewable energy sources for enhanced sustainability
