# Installing

You're best using the "One-line" install method if you want all of the UART serial configuration for the PMS5003 particulate matter sensor to run automatically.

**Note** The code in this repository supports both the Enviro+ and Enviro Mini boards. _The Enviro Mini board does not have the Gas sensor or the breakout for the PM sensor._

## One-line (Installs from GitHub)

```
curl -sSL https://get.pimoroni.com/enviroplus | bash
```

**Note** report issues with one-line installer here: https://github.com/pimoroni/get

## Or... Install and configure dependencies from GitHub:

* `git clone https://github.com/pimoroni/enviroplus-python`
* `cd enviroplus-python`
* `sudo ./install.sh`

**Note** Raspbian Lite users may first need to install git: `sudo apt install git`

## Or... Install from PyPi and configure manually:

* Run `sudo pip install enviroplus`

**Note** this wont perform any of the required configuration changes on your Pi, you may additionally need to:

* Enable i2c: `raspi-config nonint do_i2c 0`
* Enable SPI: `raspi-config nonint do_spi 0`

And if you're using a PMS5003 sensor you will need to:

* Enable serial: `raspi-config nonint set_config_var enable_uart 1 /boot/config.txt`
* Disable serial terminal: `sudo raspi-config nonint do_serial 1`
* Add `dtoverlay=pi3-miniuart-bt` to your `/boot/config.txt`

And install additional dependencies:

```
sudo apt install python-numpy python-smbus python-pil python-setuptools
```
