 As always there are some improvements that can be made. It would be better to use an infrared camera so even when it's dark the pictures are visible. Also for the current design of the house there can be some improvements by providing more holes so it has more ventilation and it wont accumulate water. As always there are some improvements that can be made.

 +=== 4.2. Recomendations===
 +  * Perform measurements to make decisions related to the energy efficiency of the project.
 +  * PCB design to allow better access and manipulation of essential elements of the project.
 +  * Make improvements to the code dedicated to upload the photo to google drive to minimize errors.
