[time-nuts] Temperature (environmental) sensors

[Bob Camp]

Hi

There is an ever increasing pool of good sensors to put into something like this. 
(More so for temperature and pressure. Humidity still is a bit of an issue.)
There’s not a lot to interface between the sensor and a USB “chip”. It’s surprising 
that there aren’t more cheap / high accuracy choices out there.
