Offbrand DHT11 Not working #93

I have an off brand DHT11 module that I got in a variety pack on amazon. I have tried many different configurations and GPIO pins but cannot get it to read.

I keep getting DHT Sensor not found, check wiring

The module has a different pinout order (VCC, Data, GND). I have wired it up properly.

I have tried both 3.3v and 5v

Maybe I am missing a resistor? Although I read the module on a board has a built in resistor.

From other threads I have read it seems like it could be the refresh rate of the data.. I tried changing the 18ms to 01ms as another suggested and it did not fix.

My next approach was to unsolder the sensor itself and wire it up as is with a resistor.

Did you manage to get this working? I'm having the same issue with 4 off-brand DHT11 sensors and 4 sets of wires for them. I'm finding it hard to believe that all of them are broken.
