Natural ventilation system

Concept

The aim of the project is to program a system for the natural ventilation of facilities with constant problems with high humidity level and temperature such as SPA centers, aquatic sport centers etc. Additionally it would control the air quality and congestion and thereafter automatically control the airflow between the inside and the outside. The mission was to program and design kinetic valves that would constantly move while the conditions are unfavorable.

concept diagram

Components ands sensors used for realization are Arduino uno board, breadboard, jumper wires, three led pins and three resistors 2200, servo motor with the idea of moving the valves, air quality sensor MQ135 and temperature and humidity sensor DHT11.

Future steps

In the future the project can turn to controlling the windows and ventilation according to the outside conditions such as rain, strong wind, snow etc.
