Hello John,

I connected a DHT11 sensor to my ESP32. The sensor will not be found.
I checkt the signals with the Oszilloskop.
The SW is doing the Pulldown but it is a little bit short. In the specification of DHT11 the Low time should be >18ms

The low time by ebusd is only 500µs. Can that be adjusted?
