This is very simple and small post but always simple and small things make smart and enterprise products. Any way it's my dream that i write a program from that i can check my подключение dht22 кatmega8 temperature and humidity instead of watching from small devices.
I am using DHT22 Temperature and Humidity sensor with Arduino UNO R3 and getting it's data from Arduino Подключение dht22 кatmega8 Monitor.
Before i go to подключение dht22 кatmega8 step i think i need to tell you some thing about DHT22. It's Humidity Range is 0-100% and Temperature range is -40 - 125°C that's why I prefer DHT22 as compared to DHT11.
For Complete steps, setup & output please watch the video.
1x Arduino/Genuino UNO
1x DHT22 Sensor
1x Bread Board
3x Jumper Wires
Let's Begin buddies.
First Pin is a VCC connect it to 5V.
Second Pin is Data Pin Connect it to Digital Pin 7.
Third Pin is called NC but i don't know why it's their i did not used it.
And Finally Fourth Pin is Ground Pin my favorite Pin.
Now upload the code to arduino подключение dht22 кatmega8 wait for .
