Write a program for arduino communicating with Sensirion SHT4x using I2C. The serial data between arduino and pc-host should be binary ascii and optimized for being handled by labview
To communicate with the Sensirion SHT4x sensor using I2C on an Arduino and send the data to a PC host in binary ASCII format optimized for LabVIEW, you'll need to follow these steps:

1. **Set up the Arduino with the appropriate libraries.**
2. **Initialize the I2C communication with the SHT4x sensor.**
3. **Read temperature and humidity data from the sensor.**
4. **Send the data to the PC in a binary format suitable for LabVIEW.**

### Required Libraries
You'll need the `Wire` library for I2C communication and the `SHTSensor` library (or similar) to communicate with the SHT4x sensor. Ensure you have the required library installed in your Arduino IDE.

### Arduino Code
Here's a sample code that performs the above tasks:

```cpp
#include <Wire.h>
#include <SHTSensor.h> // Make sure you have a compatible library for SHT4x

// Create an instance of the SHT sensor
SHTSensor sht;

// Define I2C address for SHT4x (usually 0x44)
#define SHT4x_ADDRESS 0x44

void setup() {
    Serial.begin(115200);
    Wire.begin();
  
    // Initialize the sensor
    if (!sht.begin(SHT4x_ADDRESS)) {
        Serial.println("Sensor not found!");
        while (1);
    }
}

void loop() {
    // Read
  Here is an example program for an Arduino board communicating with a Sensirion SHT4x temperature and humidity sensor using I2C and sending binary ASCII data to a PC host for further processing in LabVIEW:
```scss
#include <Wire.h>

#define SHT4X_I2C_ADDR 0x40 // I2C address of SHT4x sensor

// Define the structure for holding the sensor data
struct sensor_data {
  int temperature; // Celsius
  int humidity; // %RH
};

void setup() {
  // Initialize I2C interface
  Wire.begin();

  // Set the I2C address of the SHT4x sensor
  Wire.setAddress(SHT4X_I2C_ADDR);
}

void loop() {
  // Read the temperature and humidity data from the SHT4x sensor
  struct sensor_data data;
  Wire.beginTransmission(SHT4X_I2C_ADDR);
  Wire.write((char)0x00); // Read temperature
  Wire.write((char)0x01); // Read humidity
  Wire.endTransmission();

  // Parse the sensor data
