This is a simple project which reads the current amount of visitors in the RWTH gym from their website and saves it in a database. The data is then visualized in a simple web interface. The website is available here.
The only challenge here was that the visitor count is provided as an image. I had to use OCR to extract the number from the image. I used the pytesseract
library for this. Also since there are not many possibilities for how many visitors there can be, I save the images in a hash map so that I don't have to OCR the same image again.
After making this I found a project by dorian-K, that does pretty much the same thing. You can check it out here
