| - | Overall the implementation of the system is not done. I made the neural network for detecting bears, and put it on the ESP32-CAM. The ultrasonic sensor also works well. The problems I am currently facing are connecting to the Firebase and to the SMTP server. I was able to connect to Firebase with the current ESP32-CAM and upload images unitil recently, as can be seen in the image from chapter 3.2. One challenge I encountered on working on this project were the faulty ESP32-CAMs (one arrived broken and 2 became broken after a few hours of usage). As I can't see exactly the images taken is also hard to adapt the neural network for correct inference on the board. | + | Overall the implementation of the system is not done.
