Story

In this project, an approach based on a combined model for dynamic and automatic regulation of indoor temperature is proposed. The proposed project performs indoor temperatures forecasts that are used to manage the on/off switching of the Air conditioner system and the regulation of the inlet Temperature.

Air temperature control inside buildings is not easy if the purpose is the maintaining of thermal comfort conditions. The Arduino UNO and TMP36 Temperature sensors are the devices used to regulate the indoor temperature parameters. It is low-cost and reusable. It is necessary to consider the increase of power consumption, due to the setting choices of the users inside the building. Therefore, it is necessary to develop smart strategies for thermal control in order to obtain internal comfort automatically. It will also employ an audible alarm to alert people and emergency services when the temperature exceeds 55 degrees Celsius or 131 Fahrenheit.

In this project, if the inlet temperature below 25 degrees Celsius or 77 Fahrenheit, the Air conditioner systems of the building are turned off and the building will be in power-saving mode. And if the inlet temperature is between 25 degrees Celsius or 77 Fahrenheit to 55 degrees Celsius or 131 Fahrenheit, the Air conditioner systems of the building are turned on. And if the inlet temperature exceeds 55 degrees Celsius or 131 Fahrenheit, the system will employ an audible alarm to alert people and emergency services.
