int humidityValue = 0;
float humidityLevel = 0.0;
void setup() {
  Serial.begin(9600);
}
void loop() {
  humidityValue = analogRead(humidityPin);
  humidityLevel = (humidityValue  100.0) / 1023.0;  // Convert analog value to humidity level (0-100% RH)
  Serial.print("Humidity: ");
  Serial.print(humidityLevel);
  Serial.println(" %RH");
  delay(1000);
}
```
Example 2: Interfacing with Raspberry Pi (Python)
In this example, we'll demonstrate how to connect the ZFX-13001 to a Raspberry Pi and read the humidity level using Python.
Hardware Connection:
Connect VCC of ZFX-13001 to 12V DC power source
 Connect GND of ZFX-13001 to GND of Raspberry Pi
 Connect OUT of ZFX-13001 to any available analog input pin (e.g., GPIO 18) of Raspberry Pi

import RPi.GPIO as GPIO
import time
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Define analog input pin
humidity_pin = 18
# Read analog value from humidity sensor
def read_humidity():
  GPIO.setup(humidity_pin, GPIO.IN)
  humidity_value = GPIO.input(humidity_pin)
  return humidity_value
while True:
  humidity_value = read_humidity()
  humidity_level = (humidity_value  100.0) / 1023.0  # Convert analog value to humidity level (0-100% RH)
  print(f"Humidity: {humidity_level:.2f} %RH")
  time.sleep(1)
```
Note: In both examples, the output voltage from the ZFX-13001 is read as an analog value and then converted to a humidity level (0-100% RH) using the specified conversion formula.
