Arduino Project: Temperature and Humidity monitor Tutorial with DHT11 (or DHT22) sensor LCD shield.
Arduino Project: Temperature and Humidity monitor Tutorial using DHT11 (or DHT22) sensor and LCD shield.
In this video we are building a Temperature and humidity monitor, using an Arduino Mega, an LCD Display Shield with a DHT11 sensor. If you have a DHT22 sensor, the wiring is exactly the same.

My name is reghu I like your video too
I got the code to compile without any issues, but I am getting the readings as T: NAN C H: NAN. I know that NAN stands for Not a Number, but I don't know how to resolve the issue. Could this be indicative of a bad sensor? What else could cause this?
DHT dht(DHTPIN, DHTTYPE); —-> 'DHT' does not name a type ?
Outdoor DHT sensor doesnot read minus values at winter.
Please ,how can we fix the temperature from -50 to +50
Hello . Thank you for your nice explanation.
I have a question:
Are the sensors like LM35 and DH11-22 accurate and reliable?
Are it need to calibrate?
thank you
is it necessary to calibrate the sensor or it is auto calibrated??

Good video
Hello. When I Try to download the code from the website, I am having this problem: The requested URL /Arduino/WeatherStation/code.zip was not found on this server.
nick ozzie here, have the librarys changed. i built this one about 3 obnths ago and now i get a shit load of errors with the libs?
can i use with arduino uno
can we use arduino uno r3 for this and can it connect with dht11

Errors
how diplay data of this sensor on web page using shield ethernet ?
please make a new one with the new lib and a dht22
can i use the same code for arduino uno r3 (except the pin mode. i will change it.)
Question….The dhtt22 working great so somewhat…they are about 10 to 20ft away and I tested voltage. the voltage on the far one is 4.9v. one problem I am having is that sometimes the the temp drop from 70 degrees to 51.1 degrees. is there a way to correct this problem?
WORKS EXCELLENT ..THANKS BUT IF I WANT IN FARENHEIT..
Your fucking setup melted my sensor
i am using a arduino uno with lcd screen and the same sensor as in video but i donot have same inputs for sensor on arduino can anyone help?
this is the error i get when verify… can anyone help me?

hi i have a question . i need to implement Temperature and humidity monitor, on atmega2560 with C language. do you think this source code will help me?
thnx. i m getting output. but temperature is not varying very hardly!!!
Is this compatible with a raspberry pi 3?
Goog evening, I download, and upload ( educ8.com/arduino/weatheratst, ) but not working. come error message. please, help me
is LCD TFT Display applicable for the arduino ? do they differ in coding?
can you help me about a temperature controller using atmega16 and DHT11 through keypad and lcd?
