I have disabled the sensors since there are so many different offerings now in the market that let you monitor humidity and temperature.
There are two sensors on the Raspberry Pi logging the pressure, temperature and humidity. They are a BMP085 and a AM2302. All the data is logged every 15 minutes and displayed using Python code. Below there are three plots of temperature and pressure for the past 24hours, past week and total record (for the year). These graphs are updated every 5 minutes, once a day and once a week respectively.
Please click on image to see the most recent plot. The plots are not updated on this page that frequently. Please note that from end of August 2016, the temperature record is now from Michigan. Also the temperature was measured inside for a large amount of 2017 (temperature stable inside).
