Purpose

I want to know what the temperature is outside

Components

• Sparkfun Redboard
• Sparkfun Weather Shield
• Made in China DHT11
• DHT11
• DS18B20 in a 'outdoor' package

Parameters

The following parameters are recorded and stored. Missing, or invalid, values are thrown away:

• Pressure (barometric, mbar) & pressure sensors' temperature
• Internal humidity & temperature
• External Humidity & temperature
• External Temperature
• Roof Temperature

Arduino output

The system makes a measurement roughly every 5 seconds, and the host OS pushes it into brianiac for posterities sake.

Format

A typical data frame emitted over the serial line looks something like this (with extra spaces, newlines, etc) (:

  {
    "pressure_mbar": 843.5235,
    "pressure_temp": 25.3252,
    "ihumidity": 56.343,
    "ihumidity_temp": 25.232,
    "humidity": 60,
    "humidity_temp": 25,
    "temperature1": 35.2213,
    "temperature2": 35.2213,
  }
