My esp32 weather station web server is not working properly

[AESIRAEROSPAZIALE]

Hi!
I've been trying for days to build a weather station with an anemometer and dht22. My esp32 can connect to the wifi, thw web page is shown correctly but wind speed data and terrain humidity doesn't work... can somebdy help me please? Sorry for my english
