Automatic Exhost Fan Controller With Pollution Sensor

Description

Automatic Exhaust Fan Controller with Pollution Sensor

The Automatic Exhaust Fan Controller with Pollution Sensor is an intelligent air quality management system designed to automatically regulate ventilation based on the level of air pollution in an environment. It helps maintain clean and healthy indoor air by detecting harmful gases, smoke, or poor air quality and activating an exhaust fan when needed.

This system uses a pollution or gas sensor (such as MQ series sensors) connected to a microcontroller that continuously monitors air conditions. When pollution levels exceed a predefined threshold, the controller automatically switches ON the exhaust fan. Once the air quality improves, the fan is switched OFF, ensuring efficient energy usage and optimal air circulation.

Key Features:

• Real-time air quality monitoring using pollution sensors
• Automatic ON/OFF control of exhaust fan
• Microcontroller-based smart decision system
• Energy-efficient operation
• Adjustable pollution threshold levels
• Compact and easy-to-install design

How It Works:

The sensor continuously measures air quality parameters such as smoke, harmful gases, or pollutants. The microcontroller processes this data and compares it with a set limit. If the pollution level rises above the threshold, the exhaust fan is activated automatically. When the air becomes clean again, the system turns the fan off without manual intervention.

Benefits:

• Maintains healthy and breathable indoor air
• Reduces manual effort in controlling ventilation
• Saves electricity through smart automation
• Ideal for kitchens, bathrooms, offices, and industries
• Improves overall environmental comfort and safety
