This temperature sensor has two versions: a probe version (WN34S) and a cabled version (WN34L) as your selection. The probe sensor is mainly used to test the soil temperature, while the cabled version is mainly used to test water temperature.
The two versions will be recognized as the same sensor type by the software. If you purchased both, they will share the eight channels together and the total supported quantity of the two sensors could not exceed eight for one receiver.
