## Supported sensor types

| Sensor name | I²C Addresses |
| ------------- | -------------- |
|[SHT40](https://sensirion.com/products/catalog/SHT40/)| **0x44**, 0x45|
|[SHT41](https://sensirion.com/products/catalog/SHT41/)| **0x44**, 0x45|
|[SHT45](https://sensirion.com/products/catalog/SHT45/)| **0x44**, 0x45|

The following instructions and examples use a *SHT40*.

## Connect the sensor

You can connect your sensor over a [SEK-SensorBridge](https://developer.sensirion.com/sensirion-products/sek-sensorbridge/).
For special setups you find the sensor pinout in the section below.

## Contributing

We develop and test this driver using our company internal tools (version
control, continuous integration, code review etc.) and automatically
synchronize the `master` branch with GitHub. But this doesn't mean that we
don't respond to issues or don't accept pull requests on GitHub. In fact,
you're very welcome to open issues or create pull requests :-)

### Check coding style

The coding style can be checked with [`flake8`](http://flake8.pycqa.org/):
