Weather Sensor Installation
Choose Location
• Select a convenient outdoor location in close proxim-
ity (wire-run distance is 200 feet maximum) to the ESP-
SMTe controller. Place in an unobstructed area away
from reflective heat so that the unit can provide accu-
rate on-site temperature and rainfall measurements.
• Mount the unit at least 6 feet above the ground sur-
face to accurately measure ambient temperature. Sug-
gested installation locations include the eave of a resi-
dence roof, a wooden fence post, etc.
• The sensor mounting bracket is designed to mount
on any vertical surface. Easy adjustment of the mount-
ing arm ensures the installed sensor is level. UV rated
#16AWG or #18AWG wire is recommended for the com-
munication wires if more than 25 feet is required.
Sensor Mounting Options
Do’s
• Mount the weather sensor at least six feet
above grade.
• Ensure that sensor is free from obstructions
to allow for collection and accurate mea-
surement of rainfall.
• Sensor does not require direct sun to work
correctly provided any shade or other
obstruction does not block rainfall.
Don’t’s
• Do NOT install sensor in a location where
spray from a sprinkler will collect in the sen-
sor.
• Do NOT install the sensor where rainfall will
be reduced or blocked from entering the
sensor funnel
• Do NOT install the sensor where it will be
impractical to service – the rain sensor may
require cleaning depending on the amount
of leaves, dust, etc that may collect in the
debris screen, funnel, or tipping bucket rain
sensor.
