Our Google Colab Notebook were we trained the demo model:

We found a fire images data set that we used to train the model.

https://github.com/DeepQuestAI/Fire-Smoke-Dataset

Which had only 3000 image however we managed to get around 80% which is great given the size of the data and we were training on colab.

We also used MIT app inventor for making the app mockup.
