in a plastic bag.
4.2 Use SCWin to Program Datalogger and Generate Wiring
Diagram
The simplest method for programming the datalogger to measure the sensor is
to use Campbell Scientific’s SCWin Program Generator (Short Cut).
Short Cut requires the use of a soil temperature sensor before the
253 or 257 sensor is added. This is needed because there is a
temperature correction factor in the equations that convert sensor
resistance. In these Quickstart examples, a 107-L temperature
probe is used to measure soil temperature. NOTE
