# MCP3008
This plugin adds support for the MCP3008 Analog Digital Converter to nymea.
> Note: This plugin will only work on the Raspberry Pi
## Supported Things
* MCP3008
## Requirements
* The MCP3008 must be wired up properly to the SPI interface.
* The package “nymea-plugin-mcp3008” must be installed
