I want to read PWM output signal which I got from a sensor. Is there any way to give PWM signals as input to Raspberry pi 4B?

  • You need to clarify the characteristics of the PWM you want to read.

PWM is a digital signal.

You could (at least in principle) monitor to detect the proportion of time it is HIGH.

If I wanted to do this I would write code to detect rising and falling edges and times.

I am unaware of any existing code although Joan's DHT temperature humidity code would provide an excellent starting point.
