How do I connect the dht11 library for this

i used chatgpt to make the code

C:\Users\jyd\Documents\Arduino\Dht11\Dht11.ino:1:10: fatal error: dht.h: No such file or directory
#include <dht.h>

#include <dht.h>

// Define DHT sensor type and pin
#define DHTPIN 2
#define DHTTYPE DHT11  // Use DHT22 if you have one
DHT dht(DHTPIN, DHTTYPE);

// Define RGB LED pins
#define RED_PIN 9
#define GREEN_PIN 10

void setup() {
  Serial.begin(9600);
  dht.begin();
  
  pinMode(RED_PIN, OUTPUT);
  pinMode(GREEN_PIN, OUTPUT);
  pinMode(BLUE_PIN, OUTPUT);

  Serial.println("Temperature & Humidity RGB Indicator");
}

void loop() {
  // Read temperature and humidity
  float temperature = dht.readTemperature();
  float humidity = dht.readHumidity();

  // Check if the readings are valid
  if (isnan(temperature) || isnan(humidity)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }

  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.print(" °C, Humidity: ");
  Serial.print(humidity);
  Serial.println(" %");

  // Determine LED color based on temperature
  if (temperature < 20) {
    setColor(0, 0, 255);  // Blue for cool temperatures
  } else if (temperature >= 20 && temperature <= 30) {
    setColor(0, 255, 0);  // Green for comfortable temperatures
  } else {
    setColor(255, 0, 0);  // Red for high temperatures
  }

  delay(2000);  // Wait 2 seconds before next reading
}

// Function to set RGB LED color
void setColor(int red, int green, int blue) {
  analogWrite(RED_PIN, red);
  analogWrite(GREEN_PIN, green);
  analogWrite(BLUE_PIN, blue);
}

Have you installed dht.h library?

in not, read:

https://docs.arduino.cc/software/ide-v1/tutorials/installing-libraries/

Have you installed a library for the DHT11 sensor ? If so, which one ?

What does your new friend ChatGPT have to say about the error ?
