DAVIS External Temperature Sensor with RJ Connector User Manual
External Temperature Sensor with 25-Foot Cable
Installation Manual
The external temperature sensor may be used with
the wireless Davis Weather Envoy (product no.
6316), Envoy8X (product no. 6318), Wireless
Temperature Station (product no. 6372), or the
Anemometer/Sensor Transmitter Kit (product no.
6330). The sensor may be used to measure air,
soil, or water temperatures. It comes with a 25'
(7.6 m) cable
.
Tools and Materials Needed
You may need some of the following tools and materials to complete your
installation. Please be sure you have everything you need before beginning.
• Shovel or spade to dig hole for sensor if using as a soil temp sensor
• Metal or plastic conduit to protect cable from rodents
• Cable clips or weather-resistant cable ties with screw holes or other means for
mounting to secure cable
Testing the Sensor
Test the sensor before installing it.
1. Attach the sensor cable to the appropriate connector on the Envoy or Temperature
Station. Consult your Envoy or station manual for more information.
2.
Press the appropriate key on your console as necessary to make sure you are getting an outside temperature reading on the console. Or, if not using a console,
check the Envoy via software. The sensor will report as “inside temperature.”
Choosing a Location for the Sensor
Use the suggestions below to find a suitable location in which to mount the sensor.
Care taken in choosing a location improves the accuracy, reliability, and durability of
the sensor. The ideal location would be on the NORTH SIDE of the building (south
side in the Southern Hemisphere).
Note: When choosing a location for the sensor you should take into consideration the objects
nearby. Objects which heat up in direct sunlight or produce radiative cooling effects may
affect temperature readings by changing the surrounding air temperature.
Look for a location which satisfies the following requirements:
• Place the sensor in a location where it will not be in direct sunlight and where it
will have limited exposure to reflected sunlight.
• Limit the exposure of the sensor to the open night sky.
• Place the sensor at least 5 feet from man-made sources of heat.
• Keep the sensor away from AC power lines.
• If possible, place the sensor at least 5 feet from any surface which is exposed to
direct sunlight because the heat from this surface may affect air temperature
readings in the vicinity.

Installing the Sensor
• Place the sensor in a location at least 10 feet away from lights or lamps.
• If you are unsure about a location's exposure to the night sky, check for dew at
that location on a light dewy morning. If the area is dry, the location should
work well.
• Keep the sensor and most of the cable at least 10 feet from 110 Vac, 60Hz utility
power. Do not run the sensor cable parallel to house wiring. Mount the sensor at
least 30 feet from high-voltage power lines and transformers.
