I have run some tests by changing the two timer values within the DHTxx.cpp file.
Initially set to 400 per your suggestion. I get a single reading only and no further serial output data comes (left for 5 minutes before tying something else).
I also tried values of 300, 500, 260 with the same results: one single reading only displayed through the serial output.
Trying value 255 provides regular serial outputs, but only the initial output is the correct value.
I also tried lowering the timer value: 200, 150, 100 which provides regular serial outputs, but only the initial output is the correct value.
Serial output at timer values of 400:
Kind regards,
Matthew
