INSTALLING SENSAIRY HUD
SensAiry HUD comes with 3M Very High
Bonding (VHB) tape affixed at its base.
We recommend attaching HUD on your
vehicle’s windshield.
Choose a location on windshield close to
dashboard such that your windshield view
is not blocked.
Make sure that supplied USB cable can
reach to your USB connector on your
vehicle and HUD.
2
Clean the surface of windshield where
HUD will be fixed so that it is dust free.
This is a critical step as bonding strength
of tape depends on dust free surface.

Note: Affixing SensAiry HUD on car
dashboard is not recommended as
dashboard surface is usually made of low
surface tension material. Due to this, the
tape may not bond properly and may come
off over time.
Place the HUD on the cleaned surface
and press the base with tape firmly so
that tape is bonded to windshield.
Wait for 10 minutes.
To adjust the angle of view, press the
base of HUD with one hand and adjust
HUD display using the other.
Carefully peel the protective layer on
the tape.

Home Screen
Tyre Pressure data is shown in bigger number in units of psi. Maximum
pressure that can be displayed is 99 psi and minimum is 0 psi. Next to tyre
pressure, tyre temperature is shown as superscript in units of Celsius.
Maximum temperature displayed is 99°C and minimum is -40°C.
In case of Low Pressure of a tyre, pressure value and tyre icon of the
associated tyre will blink and Low Pressure alert message in red will be
displayed next to that reading. HUD also gives audio alert using built in
buzzer.
In case of High Pressure of a tyre, pressure value and tyre icon of the
associated tyre will blink. HUD also gives audio alert using built in buzzer.
SensAiry HUD is powered using the supplied USB cable. HUD turns on when
USB cable is connected to the power source. HUD can display data from 4 tyres
at a time.
Using / , you can navigate to other screens to view the sensor data
of other tyres. If you have more than 5 sensors configured, screen number of
current screen position will be displayed for 1 second before sensor data is
shown.

As soon as HUD is turned on, dashed lines will be displayed by default
for pressure and temperature. Soon after HUD receives data from
sensors inside tyres, dashed lines will be replaced with pressure and
temperature values. It may take up to 3 minutes to display pressure and
temperature data of all tyres.
If HUD cannot communicate with a sensor for more than 24 hours,
CHEC message will be displayed on that corresponding tyre.
FEATURES AND TIPS
When audio alert is made, pressing the button will mute it
for 1 hour.
In case of Low/High Temperature of a tyre, temperature value and tyre
icon of the associated tyre will blink. HUD also gives audio alert using
built in buzzer.

To customize safe zone alerts, brightness
control etc., please continue reading the
following sections.
Setting Safe Zone
You can set pressure and temperature safe zone as per your needs by setting
lower and higher threshold values by following below instructions. When
pressure or temperature of a tyre goes beyond this safe zone, HUD will alert you
with audio alarm and visual notification.
Minimum Brightness Set Brightness
Press button to see last updated time of each sensor. Last updated
time will be displayed where temperature is displayed and it will
be displayed for 90 seconds. Use this feature for troubleshooting purpose
to make sure sensors are communicating with HUD. Press button
anytime to display temperature again.
During dark time, if the display is too bright, you can instantly reduce
the brightness by pressing button. To come back to currently
saved brightness value, press button again.

To find out sensor IDs of sensors installed in each tyre, Identify Sensor
operation must be performed. Option 4 under will let you identify
sensor IDs in each tyre and reconfigure the display appropriately.
Please note that this operation involves releasing at least 5 psi of air on
each tyre. So please ensure to perform this operation at a gas station
with access to air pump or if you have portable inflator at home.
Note: ID operation must be performed only for sensors that are already
configured in HUD. This is because calibration information has to be
retrieved. Do not install a new sensor or replace a malfunctioning
sensor with a new one without adding that sensor in HUD using ADD
operation (option 5 under ) or by first pairing in SensAiry app
on your phone.
Press button to save and go back to previous screen.
Identify Sensor
Press button from home screen. By default, you will be shown
option 1.
13

Use / to navigate to the tyre to identify its sensor.
Once you are in the desired tyre location, press button to
initiate ID operation. During ID operation, all tyres except currently
selected tyre will be hidden.
Press to start identifying sensors.
By default, last 4 digits of sensor IDs will be displayed with first tyre
selected. Selected tyre will blink. If HUD is paired with more than 5
sensors, there will be a superscript indicating the tyre number which
will display for 1 second.
Press to move to option 4 to identify sensors as shown below.
14

Release at least 5 psi of air from the selected tyre without pause and
wait.
System will identify the sensor and display the last 4 digits of the
sensor ID in HUD.
Note: If the detected sensor ID is already associated with a different tyre,
then the Sensor IDs will be swapped.

Add Sensor
Option 5 under lets you add and configure a new sensor to a tyre.
You can add up to 20 sensors per HUD.
If HUD detects a sensor that is not already configured in HUD, it will
display do GET message. This message is displayed under assumption
that you have paired your sensor in SensAiry app on your phone. In this
case, using GET operation (option 7 under ), you can transfer
sensor details to HUD.
Press button to go back to previous screen.
Perform the above operations to find out sensor IDs of all tyres.
Press button from home screen. By default, you will be shown
option 1.
Press to move to option 5 to add a sensor as shown below.

activate it and wait.
If there are tyres with sensors present already, HUD by default show
the first available tyre without any sensor. Using / , you
can select other available tyres that can be paired with sensors. All
tyres with sensors present will display last 4 digits of sensor IDs.
If HUD is paired with more than 5 sensors, there will be a superscript
indicating the tyre number which will display for 1 second.
