DHT11 and DHT22

[distans]

When using DHT11 and DHT22 sensors it might be a good idea to use Arduinos libraries instead of Adafruits to minimize the reading time. Check out the last couple of post in this thread:

Blynk and While (Alternatives)

I think I found the culprit for the high latency! Since the sensors are very popular and widely used, others may find this to be of interest. If you Google DHT22, chances are you’ll end up at Adafruit’s homepage and consequently pick their library. In the DHT.cpp from their library you find this: `pinMode(_pin, INPUT_PULLUP);` and // Go into high impedence state to let pull-up raise data line level and // start the reading process. digitalWrite(_pin, HIGH); delay(250); This doesn’t…
