Use DHT22 (Temperature and humidity) Sensor with ESp32|Wokwi Simulator

Hello friends welcome back in today's video we are going to see how to use dht22 temperature and humidity sensor with esp32 we will display these values on i2c LCD we are using here walk V simulator so let's get started first we will add dht22 sensor to the design board click on question mark to get more info about the dht-22 sensor see the pin outs now let us do the connections now add 16 by 2 LCD which has i2c interface connect VCC and ground to the LCD and then interface it with esp32 so connections are done let us go to the coding part add the libraries for dht22 and LCD from library manager config LCD as 16x2 LCD i2c pins are connected to the pin 21sda and pin 22 scl of esp32 DHT pin is connected to 15 pin of esp32 DHT and LCD and serial Port are initialized in the setup section in Loop the humidity and temperature values are read and displayed on LCD and printed on serial monitor let us start the simulation the temperature and humidity values are shown on LCD and serial monitor let us vary the temperature and humidity so that's it for today in this video we have seen how to use dht22 sensor with esp32 thanks for watching the video if you like the video then please press like button please share this video with your friends and do not forget to subscribe to this channel thanks again and have a good time
