Why do my modules read different temperatures even though they are in the same environment?

The sensors are accurate to within +/-2°C over a range of 5°C - 60°C. To account for any Module-to-Module differences in temperature sensing capability, the GPM software provides a calibration screen that can be used before data recording begins. Refer to the Instrument Software Functionality section of the RF Operator's Manual for details about calibrating the temperature sensors.
