Install the SHT Driver

The driver installation consists of creating a Python virtual environment, activating it, and installing the driver using pip.

Create a Python virtual environment:

python -m venv .venv

Activate the virtual environment:

source .venv/bin/activate

.venv\Scripts\Activate.ps1

.venv\Scripts\activate.bat

Install the driver:

python -m pip install sensirion_i2c_sht

Use the SensorBridge on Windows

Install the driver for the Sensirion SEK-SensorBridge:
```
python -m pip install sensirion-shdlc-sensorbridge
```
Connect the SEK-SensorBridge to your PC over USB.

If the SEK-SensorBridge is not detected by your system, follow the SensorBridge FTDI Driver Installation.
Connect the SHT sensor to the SEK-SensorBridge.
Run an example script in the activated virtual environment.

By default, the script assumes that the SensorBridge is connected to the COM1 serial port. If a different port is used, specify it with the --serial-port parameter:
```
python examples/example_usage_sensorbridge_s.py --serial-port <your COM port>
```
