Thermal Imaging Phone Camera

I have a 100 year old house that can be drafty and hard to heat in the winter. I have been wanting a thermal imaging camera to help find leaks ever since we bought this house. So I finally just made my own.The temperature readings are overlaid onto the phone's camera display. The display is adjustable for different temperature ranges and can show the numeric reading for every zone or just 1.
