DHT22 Sensor Tutorial || How to Interface DHT22 with NodeMCU/ESP8266

In this video, you will learn how to interface DHT22 or DHT11 humidity and temperature sensor with NodeMCU or ESP8266 to design a very accurate Thermometer and Hygrometer.
DHT Series offers their next generation of temperature and humidity sensors. These sensors are very popular for electronics hobbyists because there are very cheap but still providing great performance.

The sensor can measure the relative humidity from 0 to 100% and it has an ability to measure temperature from 40° to +125°C (-40° to +257°F).

Thankyou 👍🏻 each and every concept, working is clearly explained 👍🏻👍🏻

[rajeshgattem]

Good explanation. For the first time I get to know about the working principle of temperature and humidity sensor.

[Kavitha]

Good explanation with clarity. do more and more videos

Why I got an error compiling for board NodeMCU 1.0 (ESP-12E Module)?

Great video tutorial 😍😍😍

But description 🤐🤐

[xBerto]

this does not work
error:

'dht' does not name a type
dht DHT; // Creats a DHT object

and

error: expected primary-expression before '.' token
float h = DHT.humidity; // Gets the values of the humidity
