Doors and Mechanisms

First Door

The outside of the first door relies on an RFID sensor that detects the magnetic fields of some objects. In our case, the door will open if a certain card is passed. If the card is swiped, a green light turns on at the same time as a sound. If you swipe the wrong card, another sound plays. However, the inside of the door simply depends on a button.

Second Door

This second door is somewhat more complex than the first as it depends on the other and a DHT11. This door opens when our temperature sensor (and Humidity, although it is not relevant) detects that the room is more than 25 degrees, after this, our Arduino checks that the first door is closed, if not, this door won't open.

This door has an emergency button in case an animal or some phenomenon causes an emergency state, this button is in charge of opening the second door without paying attention to the data of the DHT11 and the status of the other door.

Our Thermometer

This thermometer is based on the data provided by a DHT11 that sends the data to an Arduino to be after reflected in an Oled Display that shows us the temperature and humidity of the sites of our house.
