My First Temperature Sensor

My Tech Supplies order [1] arrived today, so this evening I made up my first temperature sensor. We got a simple sensor working along the lines of the one described the web site for the digitemp software that we are using to read the sensors from the computer.

One-Wire Prototype, View A One-Wire Prototype, View B

Footnote: [1] Some people might be amused to know that it was my original intention to buy enough parts for five sensors. However, my failure to notice that the resistors were sold in units of 100 means that I now own what will probably turn out to be (more than) a lifetimes supply of 2200 ohm resistors! ;-)
