[time-nuts] Temperature (environmental) sensors

[Adrian Godwin]

The sensor Jim linked :

 Temp/humidity with I2C interface
https://www.adafruit.com/products/1293

looks good - packaged, high res temperature, etc. It's not 'complete' in
that it's only a sensor, but you only have to attach a USB-I2C adapter.
Probably less work than connecting up the sparkfun board.
