The external temperature sensor and the stainless steel temperature probe may
be used with any of Davis’ weather stations (except the Perception II
®)
. With
the exception of the GroWeather, the sensor may be used to measure outside
temperature, though you may bury the sensor or immerse it in water to measure soil or water temperature instead of air temperature. The GroWeather™
allows you to display two separate external temperature readings (or a single
temperature reading and leaf wetness). You may use this sensor for either temperature reading. The standard version of each sensor comes with a 40’ (12 m)
cable. The industrial version comes with a 16’ (5 m) cable.

Typical Standard GroWeather/EnviroMonitor Installation
The illustration below shows a typical standard installation for the GroWeather
(used to measure air temperature), Energy EnviroMonitor, or the Health EnviroMonitor. The sensor cable attaches to connector S2 on the sensor interface
module (SIM). On GroWeather systems, the sensor can also attach to
connector S3 to measure a second temperature (such as soil temperature).
