“`cpp
#include
#define DHTPIN 4 // DHT11 connected to pin 4
#define LDRPIN A0 // LDR connected to analog pin A0
DHT dht(DHTPIN, DHT11); // Initialize DHT sensor
void setup() {
Serial.begin(115200);
dht.begin(); // Start DHT sensor
}
void loop() {
float h = dht.readHumidity(); // Read humidity
float t = dht.readTemperature(); // Read temperature
int ldrValue = analogRead(LDRPIN); // Read light level
Serial.print(“Humidity: “);
Serial.print(h);
Serial.print(” °C Temperature: “);
Serial.println(t);
Serial.print(“LDR value: “);
Serial.println(ldrValue);
delay(2000); // Wait before repeating
}
“`
This sample code demonstrates initializing both a DHT11 humidity/temperature sensor and an LDR (light-dependent resistor).
