3 ECE Department What is a thermal mapping drone (TMD?) Remote controlled quadcopter that will record and display a thermal image of the area that it has flown over

4 ECE Department What’s already out there?

5 ECE Department What makes ours different? Remote controlled (user friendly) User can map a wide range of areas Cost effective Stitching multiple thermal images together will allow a larger map to be generated without expensive equipment (i.e. satellites, high res thermal camera)

6 ECE Department Possible Applications  Homes  Forests  Oceans  Search and Rescue  Agriculture  Glaciers

7 ECE Department Focus (Home Map)  Allow user to generate a thermal map of their home’s exterior  Data will be transmitted to and processed on their computer order to analyze IR sensor’s readings  Users can discover areas where heat escapes

8 ECE Department How significant is the problem?  In New England average winter cost of heating $1400 last year.  Expected to continue to rise  10-20% home energy wasted through leak Image Source:

9 ECE Department Societal Impact  Save money  Save energy  Build more efficiently

10 ECE Department Requirements Analysis: User Specifications  2D Arial Thermal Map on a GUI  Use of Infra-Red Sensor for thermal mapping  Stable flight control  Project cost under $500 Image source:

11 ECE Department Inputs and Outputs  Inputs Radio Controller  Outputs 2D Aerial Thermal Map Image source:

12 ECE Department Requirement Analysis – Technical Specifications  Stable flight using feedback controls for the Quadcopter using Arduino microcontroller and 9 degree freedom sensor (that includes: accelerometer, gyroscope & magnetometer)  High Precision Infra-red Sensor MLX90620 that outputs temperature data in 16x4 pixel array  Data Transmission Via radio from IR-sensor mounted on the Drone to a receiver at the user’s GUI site  Web application with software to convert the data from the IR-sensor into a thermal map

13 ECE Department Design Alternatives GPS add on Inter-Drone communication Video camera Programmable flight path
