Electronic – Data logger component identification

The default firmware sends samples to the host once per second. If you need a faster sample rate, you'll need to write custom firmware (and probably some custom USB HID drivers). The MaxSonar rangefinders, available from spaarkfun or littlebird electronics, have an analog output that's perfect for the AVR stick.

Almost certainly the output from a load cell is a Wheatstone bridge whereas the output from a temperature sensor is typically a single-ended two-wire configuration that offers a resistance change with temperature or maybe a constant current output like the AD590.

This likely means that the load cell would need to be buffered with an instrumentation amplifier followed by a voltage to current generator if you are lucky to find that the temperature logger you have uses a device similar to an AD590 then you are OK - it can be done.

However, if your temperature data logger expects the input sensor to be a thermocouple of platinum resistance type gauge then you won't be successful.

Added to this, you need to provide an excitation voltage to a load cell - it is a four wire device; two wires are excitation supply and two wires are its output.
