This unit is mounted on the first step of the stairs behind my favorite chair.

This sensor is mouned on the side of my bedroom nightstand. It is close to an outside wall.

This insulated but otherwise unheated space is directly beneth a two-car garage.

This sensor is in the crawl space underneath my daylight basement. It is exposed to the outside through a half dozen ground level vents.

This is our first-ever one-wire device. It sits in the mini prototyping socket used by the usb version of the arduino software. Current placement has it on the bench, in the basement, near the window.

Merlin lives in the lower level where it can get a little chilly. We monitor his cage temperature to make sure he stays healthy.
