I want to make weather station with my raspberry pi 3b+ using my DHT11 temperature and humidity sensor so I watch many video in YouTube. I notice raspberry pi use 3.3V logic level or digital output of DHT11 is 5V. In all video I watch people connect DHT11 directly with raspberry pi. No logic level convert or resistor in between sensor or raspberry pi.
My question is if I connect 5V output of sensor connect directly with raspberry pi so it is harmful for my raspberry pi. Yes or No?
Thank you for help me.
