/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* The project shall continuously read data from */
    /* connected sensors and actuate outputs based on */
    /* predefined thresholds, ensuring real-time */
    /* responsiveness to environmental changes. */
/****** END SYSTEM REQUIREMENTS *****/

/* START CODE */

/****** DEFINITION OF LIBRARIES *****/
#include <DHT.h>    //https://github.com/adafruit/DHT-sensor-library

/****** FUNCTION PROTOTYPES *****/
void setup(void);
void loop(void);

/***** DEFINITION OF DIGITAL INPUT PINS *****/
const uint8_t myDHT22_DHT22_DOUT_PIN_D2 = 2;

/***** DHT SENSOR CONFIGURATION *****/
#define DHTTYPE DHT22   // DHT 22 (AM2302)
DHT dht(myDHT22_DHT22_DOUT_PIN_D2, DHTTYPE); // Create DHT object

void setup(void)
{
    // put your setup code here, to run once:
    pinMode(myDHT22_DHT22_DOUT_PIN_D2, INPUT_PULLUP);
    dht.begin(); // Initialize the DHT sensor
}

void loop(void)
{
    // put your main code here, to run repeatedly:
    delay(2000); // Wait a few seconds between measurements

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

    // Check if any reads failed and exit early (to try again).
    if (isnan(humidity) || isnan(temperature)) {
        Serial.println("Failed to read from DHT sensor!");
        return;
    }

    // Print the results to the Serial Monitor
    Serial.print("Humidity: ");
    Serial.print(humidity);
    Serial.print(" %\t");
    Serial.print("Temperature: ");
    Serial.print(temperature);
    Serial.println(" *C");

    // Here you can add conditions to actuate outputs based on thresholds
    // For example:
    if (temperature > 30) {
        // Code to actuate a cooling system
    }
    else if (temperature < 15) {
        // Code to actuate a heating system
    }
}
