\/\/ Initialize DHT sensor
\/\/ NOTE: For working with a faster than ATmega328p 16 MHz Arduino chip, like an ESP8266,
\/\/ you need to increase the threshold for cycle counts considered a 1 or 0.
\/\/ You can do this by passing a 3rd parameter for this threshold.  It’s a bit
\/\/ of fiddling to find the right value, but in general the faster the CPU the
\/\/ higher the value.  The default for a 16mhz AVR is a value of 6.  For an
\/\/ Arduino Due that runs at 84mhz a value of 30 works.
\/\/ This is for the ESP8266 processor on ESP-01
DHT dht(DHTPIN, DHTTYPE, 11); \/\/ 11 works fine for ESP8266<\/p>\n<\/blockquote>\n
