DHT Sensor Library does not see to work

Using Arduino Programming Questions
#1

I hope this is the correct place to post this. I have an Arduino UNO and a DHT22 temperature and pressure sensor. a few years ago I added the library and it all seemed to work fine. I’m trying again now and I keep getting errors. Any advice would be appreciated

Error Message
exit status 1
‘dht’ does not name a type

If you cant tell already I’m new :slight_smile:
Here is my code

#include <dhtnew.h>
#include <LiquidCrystal.h>

#define dataPin 10
dht DHT; **HERE IS WHERE THE ERROR IS HIGHLIGHTED **

int readData = dht.read22(dataPin);
float t = DHT.Temperature;
float H = DHT.Humidity;

int delayTime(3000);
LiquidCrystal lcd(1,2,4,5,6,7);

void setup() {
lcd.begin(16,2);

}

void loop() {

lcd.print(h);

lcd.setCursor(0,0);
lcd.print("Temperature ");
delay(delayTime);

lcd.setCursor(0,2);
lcd.print("Humidity ");
delay(delayTime);

}

Look in dhtnew.h.

What is the class called?

#3

Sorry I'm not sure what you mean. I even tried some of the examples and they didnt work

#4

#include <dhtnew.h>Find that file.
Look for the class definition.

#5

I recommend you using the DHT library from Adafruit. You can see the instruction on this Arduino DHT sensor tutorial
