I just got a couple of TEMPer1 temperature sensors, with accompanying software, and these look promising for inexpensive data logging (about $10/sensor incl s/h). These plug into the USB port and have a one meter cable to the sensor. Multiple sensors can be plugged into a USB hub, and the software will record a separate data file for each sensor. The software is reasonably configurable, such as how often to display data in the chart and how often to record data to the data file. The data file also can be sent by email to a remote computer, either automatically or manually. My graphing software easily handles the data files to produce customized charts. Other sensors and configurations are available. PCsensor
One thing I do not know is how far the cable can be extended. Extending the cable would involve cutting it (4 wires) and splicing in a longer cable section. I am going to experiment with that.
eBay is one source to get these, but there are others.
Has anyone else experimented with these?
