Review on Adafruit BME280 Temperature Humidity Pressure by Thomas Landis

The board is small and easy to wire. There are many free Python or Perl libraries on the internet that make it easy to read temperature, pressure, and humidity readings. Please note that pressure readings must be calibrated to your altitude. Output units are metric by default (as they should be) and easily converted using simple formulas. The only thing I didn't like about the fee was that Adafruit's cost was slightly higher on Revain (presumably to offset the shipping cost).
