An Advanced Smart Biotechnological Algal Plate Air Purification System for Use in Conjunction with Real-Time Air Quality Monitoring

Air pollution has become a health and environmental hazard as its effects are worsened by the increase inor pollution levels. Conventional air purification methods, although effective, are not environmentally friendly and can be expensive. We propose an Advanced Smart Biotechnological Algal Plate Air Purification System that combines the real-time monitoring of air quality with biological purification processes. An ATmega328 microcontroller, which synchronizes different parts of the system to function well together, powers the entire system. The gas sensor senses air contaminants and draws polluted air with a fan to the algal bioreactor chamber, onto which microalgae consume carbon dioxide and contaminants and output clean air. The biological system is controlled by a microcontroller where a DC fan is used to switch the flow of air in the system allowing the pollutants to be optimized to expose more and expose it to algae purification. It also handles the control of GPIO-based sensors and actuators to allow air quality metrics tracking and adaptive management. It contains an adjustable alarm and relay for turning on the fan in response to dangerous levels of pollution as well an LCD for easy reading of system status. The GPIO interface provides the ease of connecting other sensors and actuators making scalability possible for various applications. This simple and low-cost environmental friendly approach combines microcontroller-assisted technology with biological cleaning to give environmentally friendly air to urban, industrial and household consumers as the cost-effective alternative to existing conventional air purifiers.
