/* DHT Shield - Deep Sleep
*
* Displays humidity, temperature and heat index, sleeps for 10 seconds and repeats
*
* Connections:
* D0 -- RST
*
* If you cant reprogram as the ESP is sleeping, disconnect D0 - RST and try again
*
* Depends on Adafruit DHT Arduino library
* https://github.com/adafruit/DHT-sensor-library
