Execute measurements with SensorBridge

The following steps show how to use this driver on a Windows system using the Sensirion SEK-SensorBridge to execute a simple measurement.

Install the SHT4X driver and all required packages as described in Installation.
Install the driver for the Sensirion SEK-SensorBridge
```
pip install sensirion-shdlc-sensorbridge
```
Connect the SEK-SensorBridge to your PC over USB
Connect the SHT4X sensor to the SEK-SensorBridge
Run the example script from the root of the repository.

By default the script assumes the SensorBridge is connected to COM1 serial port. If this is different on your system, pass the port in use with the --serial-port parameter as outlined below.
```
python examples/example_usage_sensorbridge_sht4x.py --serial-port <your COM port>
```

Execute measurements using internal Linux I²C driver

On Linux systems it is furthermore possible to use the Linux user space I²C driver directly. How this can be done is shown in the following.

Install the SHT4X driver and all required packages as described in Installation.
Connect the SHT4X sensor to the I²C port of your system (for example to the I²C port 1 of a Raspberry Pi).
Run the example script from the root of the repository.

By default the script assumes you have the sensor connected to /dev/i2c-1. If this is different on your system, pass the port in use with the --i2c-port parameter as outlined below.
```
python examples/example_usage_linux_sht4x.py --i2c-port <your I2C port>
```
