Abstract
Research indicates that on a hot summer day with outdoor temperatures around 80◦F, the temperature measured inside an attic could be around 135◦F or more. Extreme heat causes a homeowner’s electric bill for cooling to rise and the shingles of the house to crack and fall off. Such problems make houses unsafe to live in. Due to the cracked shingles, water leaks through the rooftop causing damages like mildew and mold. In this poster, we designed and implemented an Arduino-based smart attic fan system. It uses temperature and humidity sensors to monitor the status inside the attic. If the temperature inside the attic goes too high, or excessive moisture is detected inside the attic, the Arduino controller is going to automatically turn on the attic fan. The built-in camera can take videos inside attic and use wireless communication to upload it to cloud server. The homeowner can use their smart phones to “see” the status inside the attic remotely without the need to actually climb up into the attic. In case there is a fire, the smoke detector could also sense the situation and send out alarm to homeowner’s smart phone. This can help homeowners to detect rain leakage or other hazardous situation inside the attic and take actions on time to prevent further damage to the house. Our smart attic fan system utilizes Internet-of-Things (IoT) technology to extend the life of every roof, to lessen roof repair cost, and possibly make attics habitable.
