# arduino-sensors-toolkit

This toolkit has been designed to be used with a DHT22 (humidity, temperature) and KY-037 (sound) sensors connected to
an Arduino microcontroller. It is part of a self hosting project with specific needs. Feel free to fork this repository
and update code for your needs.

### Installation

- Installation on [Debian](debian/README.md)
- Installation on [FreeBSD](freebsd/README.md)

### Configuration

An optional configuration file can be used with `--config <file>`. See [serial2mqtt.ini.example](serial2mqtt.ini.example).

### Usage

```
python3 serial2mqtt.py --help
