CONCEPT

The air quality is constantly measured with the temperature/humidity sensor and displayed on the LCD.

When the temperature is below 25°C, the green led is on. 

Once the temperature reaches 25°C or above, the red led is activated, along with a message on the display (HOT!). The motor –  in this case a fan system –  is activated to cool the space.

NEXT STEPS

The system could be implemented with a further mister device to be activated when the humidity levels are low.

This could result in a fully automated temperature and humidity control system.
