/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* turn on a relay on temperature 20 and turn off */
    /* relay with temperature 60 */
/****** SYSTEM REQUIREMENT 2 *****/
    /* Activate a relay when the temperature reaches 20°C */
    /* and deactivate it at 60°C, ensuring precise */
    /* temperature monitoring and control for optimal */
    /* performance. Utilize compatible temperature */
    /* sensors and relay modules for effective operation. */
/****** END SYSTEM REQUIREMENTS *****/

/* START CODE */

/****** DEFINITION OF LIBRARIES *****/
#include <DHT.h> // Include the DHT library for temperature and humidity sensor
#include <Relay.h> // Include the Relay library for controlling the relay

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

// Define constants
#define DHTPIN 2 // Pin where the DHT sensor is connected
#define DHTTYPE DHT11 // Define the type of DHT sensor (DHT11, DHT22, etc.)
#define RELAY_PIN 3 // Pin where the relay is connected

// Create instances of the DHT and Relay classes
DHT dht(DHTPIN, DHTTYPE); // Create a DHT object
Relay relay(RELAY_PIN, 1); // Create a Relay object with a 1-second period

void setup(void)
{
    // Initialize the DHT sensor

    relay.setRelayMode(relayModeAutomatic);

    // Check if the reading is successful
    if (isnan(temperature)) {

    } else if (temperature >= 60 && relay.getRelayPosition() == relayPositionClosed) {
        relay.setRelayPosition(relayPositionOpen); // Deactivate relay
    }
