I am trying to find these little remote button sized thermometers that I used at an old job. They interfaced via USB, through a little cradle that you plugged them into. They would measure temperature over a 24 hour (or so) period. You then take them from where you were taking the measurement and plug them back into the cradle to get the temperature over time reading. If anyone know what these are called or a website for them I would really appreciate it. I've googled it a bit, but can't find what I'm looking for. Everything that I've seen has been wired to the sensor. Thank you.
