temperature and humidity supervision System
temperature and humidity supervision System in this project temperature and humidity supervision ,this system is based on arduino as controller and DHT22 sensor interfaced with labview . first i will begin with the arduino part : to begin with lets connect the sensor to the arduino like in the picture below pin 1 to VCC (red wire) pin 2 Data pin with pin 2 inthe arduino (yellow wire ) pin 3 not used pin 4 to GND (black wire ) now the arduino code : #include <dht.h> // import library dht DHT; #define DHT22_PIN 2 // data pin of the DHT22 sensor connected to pin 2 ...
