DHT22 PROTEUS LIBRARY DOWNLOAD CODE

tweak the timings for faster processors. Note that older versions of this library took an optional third parameter to Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor Connect pin 4 (on the right) of the sensor to GROUND Connect pin 2 of the sensor to whatever your DHTPIN is NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1 Connect pin 1 (on the left) of the sensor to +5V Pin 15 can work but DHT must be disconnected during program upload. #define DHTPIN 2 // Digital pin connected to the DHT sensor

My code is IDENTICAL for sensor 3, and messing with the delays has yielded nothing. I'm using the 3.3v output from the arduino (using the 5v for the lcd display) and have wired all 3 with 10k pull up resistors to the data pins. I have switched sensors between my wiring, and the same happens.so it's not the same sensor.

I'm receiving nothing but NAN on the third sensor.

Right now, the first two sensors are working just fine. I know the code is ugly, but I need this working before I iterate it through a for loop and an array of dht objects.
