2.

 Hang the sensor from a nail, screw, or 

hook, using one or all of the three 
mounting holes on the rear of the sensor 
(mounting hardware not included).

3.

 Secure the sensor to a wall or vertical 

surface using the magnet feature with 
the included metal plate, or by placing it 
on a suitable surface (that responds to a 
magnet) without the included plate

4. 

Secure the sensor to a wall or vertical 

surface using alternative fasteners or 
adhesive methods, such as double-sided 
mounting tape or Velcro (not included).

The X3 Outdoor Temperature & Humidity 
Sensor can be installed or mounted in at 

least one of four ways:

1. 

Lay the sensor flat on any stable 

surface, or placed within an enclosure

Location & Mounting Considerations

The X3 Outdoor Temperature & Humidity 
Sensor is designed to be easy to install, 
and portable, but before installing the 
sensor, the following items should be 

considered:

While the X3 Outdoor Temperature & 
Humidity Sensor is designed for 
outdoor use, do not use the sensor 
outside of the environmental 
temperature range, per the product 

specifications (refer to the product’s 

support page). 

The sensor body is designed for 
outdoor use, but do not allow it to be 
submerged.

Do not use the sensor near sources 
of extreme hot or cold, as this can 
affect accurate ambient temperature  
readings, and in some cases may 
damage the sensor.

As with most electronic devices, 
even if intended for outdoor use, the 
useful life of the device can be 
extended if it is protected from the 
elements. Direct intense sunlight, 
rain and snow over an extended 
period can discolor or damage the 
device. Consider placing the sensor 

where it has overhead cover and/or 

protection from the elements.

Place the sensor where it will be out 
of reach of children.

Magnet-mounting method

1.

 The sensor has a built-in magnet in 

the back, to allow for mounting it directly 
to a suitable* metal surface, or the 
included metal mounting plate can be 
used for this purpose. After selecting the 
sensor location, remove the plastic 
backing from the metal plate, to expose 
the mounting tape's adhesive side. Place 
the plate at the desired location, tape 

side down, and press firmly for at least 
five seconds. (The surface should first 
be clean and free of dirt, grease/grime, or 

any substance that will impact the tape's 
adhesion to the surface. It is suggested 
to clean the surface accordingly, such as 
with rubbing alcohol, and dry it well, 
before this step). 

2.

 Check that the sensor is secure, and 

does not move easily. If the sensor does 
not seem to be secure, please mount 
your sensor per the wall-mounting 
method steps. 

*Suitable surfaces are metallic surfaces 
responsive to magnets, that allow for a 
good bond with the sensor's built-in 
magnet. Uneven, irregular, textured, 
grooved, etcetera, surfaces may not be 
suitable. Surfaces subject to vibration 
and movement are not likely to be 
acceptable. Verify the surface is suitable 
and the sensor is secure, as physical 
damage to the sensor is not covered by 
the warranty. 

Other mounting methods

Follow the manufacturer instructions if 
mounting your sensor by alternative 
methods, such as with Velcro or 
double-sided mounting tape. If using an 
adhesive method, is it recommended to 

clean and dry the surface, first. Consider 

the possibilty of replacing or relocating 
the sensor later, when choosing 
alternative mounting methods. 

Prepare to use your sensor

Allow your sensor around an hour to 
stabilize and display the correct readings 
on the LCD display and in the app. If you 
believe your sensor readings are 

inaccurate, first consult the calibration 

section of the full installation and user 

guide and/or app. 

Refer to the full Installation & User Guide 
for additional information and to 
complete the set-up and settings for 
your sensor. 

4.

 Hang the sensor from this topmost 

screw/nail/hook. If you will not utilize 

the second and third mounting points, 
ensure the sensor is secure, and proceed 
to 

Prepare to use your sensor

.

5.

 If not already performed in a previous 

step, verify the sensor is level prior to 
pre-drilling or inserting holes for the 
lower mounting points. Insert one or 
both screws through the lower mounting 
holes, tightening them and securing the 
sensor to the wall. 

6. 

Replace the access cover by pushing 

it back into place, after aligning the tab 
on each end with the matching slot in 
the sensor. Proceed to 

Prepare to use 

your sensor

.

3. 

Your mounting hardware (nails, 

screws, hooks, etc.) will vary. If using 
wall anchors, install the anchor(s) at this 
time, per the wall anchor manufacturer's 

instructions and/or per appropriate 

method for your application.  Insert the 
topmost nail, screw, or hook, in the wall, 

leaving a gap between the nail/screw 

head and the surface, as shown. 

2. 

If desired, mark or otherwise identify 

the exact position of your sensor on the 
wall, including one or all of the mounting 
points (keyhole at top, two screw holes 
at bottom). Use a level tool to ensure 
your sensor will be level, if desired.

Insert the tip of a slotted screwdriver and 
then gently twist it to pry off the battery 
access cover

Wall-mounting method

1. 

The sensor has a standard "keyhole" 

notch on the rear, at the top. This allows 
for hanging the sensor from a nail or 
screw. Additionally, there are two more 
mounting holes at the bottom of the 
sensor. The use of the second and third 
holes will result in a much more secure 
mounting method. These holes are 
hidden behind the removeable access 
cover. This cover affords protection 
against tampering and device removal 
and their use is highly recommended. 

Refer to the figure below for instructions 

on how to remove the cover from the 
bottom of the sensor. 

about 1/8th inch or 3 mm
