# Sensor Data Logger

## About

This utility translates usb mic audio into vibration data and sends it as mqtt messages. It can also read any sensor data from say `gpio` and include it in messages. Background noise cancelling can be done by adding a second mic located further from monitored source and subtracting its readings. Suitable for monitoring electric motors. Refer to source code for further information.

## Requirements

* Raspberry Pi

* USB mic

## Note for nodered users

Robust workflows can be created in `nodered` to process incoming `mqtt` messages and log these into a db. E.g. logging to a remote `mongodb` over an `autossh` tunnel.
