```c
#include <Wire.h>

// Define the I2C address of the MH13001
#define MH13001_I2C_ADDRESS 0x27

void setup() {
  // Initialize the I2C communication
  Wire.begin();
  
  // Set the relay pin as an output
  pinMode(RELAY_PIN, OUTPUT);
}

void loop() {
  // Read the humidity value from the MH13001
  int humidity = readHumidity();
  
  // If the humidity is above 60%, turn on the relay
  if (humidity > 60) {
    digitalWrite(RELAY_PIN, HIGH);
  } else {
    digitalWrite(RELAY_PIN, LOW);
  }
  
  delay(1000);
}

int readHumidity() {
  // Send a request to the MH13001 to read the humidity value
  Wire.beginTransmission(MH13001_I2C_ADDRESS);
  Wire.write(0x00);
  Wire.endTransmission();
  
  // Read the humidity value from the MH13001
  Wire.requestFrom(MH13001_I2C_ADDRESS, 2);
  int humidity = Wire.read() << 8 | Wire.read();
  
  return humidity;
}
```
### Example 2: Humidity and Temperature Monitoring with Raspberry Pi

In this example, we will use the MH13001 with a Raspberry Pi to monitor the humidity and temperature values.
```python
import smbus
import time

# Define the I2C address of the MH13001
MH13001_I2C_ADDRESS = 0x27

# Initialize the I2C communication
bus = smbus.SMBus(1)

while True:
  # Read the humidity value from the MH13001
  bus.write_byte(MH13001_I2C_ADDRESS, 0x00)
  humidity = bus.read_word(MH13001_I2C_ADDRESS)
  
  # Read the temperature value from the MH13001
  bus.write_byte(MH13001_I2C_ADDRESS, 0x01)
  temperature = bus.read_word(MH13001_I2C_ADDRESS)
  
  # Print the humidity and temperature values
  print("Humidity: {:.2f}% RH, Temperature: {:.2f}C".format(humidity / 10.0, temperature / 10.0))
  
  time.sleep(1)
```
Note: In both examples, make sure to connect the MH13001 to the I2C bus and power it with 220V AC. Also, ensure that the relay pin is connected to a suitable load, and the humidity and temperature sensors are exposed to the environment.
