Introduction
============

  Need an easy way to tell if someone is home? A way that preserves
  privacy since they can easily make it appear they are not home? Keep
  loosing your keys around the house? Can't find your keys and wonder if
  you left them at home? Anyways, whats the temperature like at home
  right now? These are all things the House Tracker 5000 can help with.

Design
======

  It's a simple idea, add to your keyring a 3.5mm jack with a DS18B20
  wired in. When it's plugged into the PCB then an WeMos D1 mini tracks
  it's presence based off the unique ID and updates a webpage with the
  temperature and when it was plugged in.

  You might even be able to guess at outside temperature based on the
  reported temperature when the device is first plugged in.

  I've yet to design the reporting webpage but plan to log time out,
  time in and temperature every so often. It's powered from the USB port
  on the WeMos so power usage is not a concern. There is also a SPI
  header, a serial header and power pins.
