ESP8266 Community Forum

I personally got a "similar" issue having a reset after 8sec when readin values from dht 22 on a V1NodeMCU (esp8266).
The way I solved it was using the D2 gpio instead of the D1.
This is absurd as on teh NodeMCU board doc both are normal gpio and I hadn't emssed myself in the hardware/softare naming.

I checked D3 and D4 didn't worked either...

==>> change digital pin can solve stuff (mysteriously to me)

DHT 11 did not transfer data after reset It helped resistor 4k7 from +3,3v to out pin and resistor 2k to ground. Resistor 2k to ground helped to start communication. data appears on oscilloscope. It's working.
