Smart Q Sensors
Smart Q Sensors are each equipped with a sophisticated microprocessor that greatly improves the
sensor’s accuracy, precision and consistency. The auto-identification circuitry dramatically simplifies
set up procedures and allows for greater flexibility when logging data.
The six inputs on Q Advanced may be used with analogue and digital sensors. Both will be recorded
side by side during logging operations e.g. whilst recording with traditional analogue sensors, a
digital sensor can be used to create a ‘blip’ on the graph to mark an event. Once a Smart Q Sensor
is connected it will automatically be detected and displayed on the LCD display.
To maintain consistency with existing software, sensor inputs 5 and 6 are dual
labelled as A and B. These inputs for are use with digital sensors which must be
connected to either Input 5:A or Input 5:A and 6:B during Timing operations.
Four sensor leads have been provided to connect Smart Q Sensors to Q Advanced.
1. Hold the Smart Q sensor housing with label on top.
2. Push one end of the sensor cable into the socket on the sensor
housing with the flat of the connecting plug facing upwards.
3. Connect the other end of the cable to the shaped input socket on
the EASYSENSE Q Advanced.
Smart Q Sensors are available to purchase separately and are not
supplied with EASYSENSE Q Advanced.
Sensors can be divided into two main types:
1. Analogue - which are used to measure physical quantities such as temperature, sound, light,
pH, etc.
2. Digital - which are switch-type sensors for measuring ON/OFF conditions such as light gates
and timing mats used for calculating time, speed and acceleration.
Please contact your supplier for an up-to-date list of Smart Q Sensors.

Ways to capture data with EASYSENSE Q Advanced
There are different ways that EASYSENSE Q Advanced can be used to collect data.
1. Real time. In this mode EASYSENSE Q Advanced is entirely driven by the software on the host
computer. The data from the sensors is transmitted immediately to the computer and displayed
on the computers screen using the applications in the EASYSENSE software. This method of
collection is useful for many classroom-based experiments.
2. Remote. In this mode EASYSENSE Q Advanced is used to collect and store data while
disconnected from the computer. Data collection can either be:
a) Setup using EASYSENSE Q Advanced menu options (e.g. Easy Log, Snapshot, Logging
or Time & Motion – see stand-alone operation on page 9).
or
b) Setup via Setup Remote in the EASYSENSE software to log data for a set time period.
The data collected in remote mode is stored in the memory of EASYSENSE Q Advanced to be
retrieved later by the computer.
Using EASYSENSE Q Advanced connected to a computer for the first
time
Step 1:
Install the EASYSENSE software, if it is not already on your computer. For details of how to install
and operate this program, please refer to the instructions provided with the EASYSENSE software.

!!The data recorded will be stored as a data set. The data set can be downloaded to the
computer for display and analysis using Retrieve remote from the Home page in the
EASYSENSE software.
EASYSENSE Q Advanced records data at a rate of 40 samples per second until it has captured
1000 samples. At this point, the sample rate halves (i.e. 20 samples per second) and alternate
samples are discarded (leaving 500 samples). It will continue at this speed until it has captured
another 500 samples (1000 total), then the sample rate halves again (i.e. 10 samples per second)
and it discards half the stored data, and so on. See page 28 for full details.
In EasyLog mode the EASYSENSE Q Advanced will stay awake until the interval between readings
reaches 5 seconds or greater – at this point it will begin to sleep between samples to conserve
battery power. When EASYSENSE Q Advanced is asleep, sensor readings can be viewed by
pressing any button to ‘wake’ it up.
Press the green button while still logging to see a logging summary i.e.
samples taken, elapsed time, current logging interval and the time started.
Press again to return to the normal screen.
When the sample interval is greater than or equal to one second (i.e. after logging for 8 minutes and
20 seconds), it is possible to download data from EASYSENSE Q Advanced to a computer (without
interrupting the recording) using Retrieve remote from the Home page in the EASYSENSE software.
The maximum duration of any one Easy Log recording is 41 days (1000 hours - 1000 readings at a
1 hour interval).
Note: If you would prefer to record for a specified time span then set up Q Advanced using Logging (see below) or the
Setup remote option in the EASYSENSE software.
Logging
In Logging mode, the total recording time, interval between readings and trigger condition can be

pointer is pointing at ‘sensor rises’ or ‘sensor falls’ as appropriate. Press
the green button to select.
Scroll though the connected sensors until the pointer is pointing at the
sensor that will be used as a trigger. Press the green button to select.
Enter the level at which the sensor will trigger the start - use the blue
buttons to scroll up or down through the numbers. Press the green
button to select a number. When the trigger level is selected press the
red button.
Note: The list starts each time at the same point (a space); use the up button to go through
the numbers, and the down button to delete (), decimal place and minus sign.
Press the green button to confirm your choice.
Logging will not start until the value rises above or falls below the set
level as appropriate.
Pre-trigger
If ‘sensor rises’ or ‘sensor falls’ has been selected as the trigger event
and the selected logging duration/interval is fast enough, an option to
set a pre-trigger will be available [None, 25%, 50%, 75%, and 100%].
Pre-trigger will cause a percentage of samples to be taken before the trigger condition is met and
the remainder to be taken afterwards e.g. if 1,000 readings are to be taken and a 25% pre-trigger
is selected, 249 readings will be taken before the trigger condition is met.
If pre-trigger readings are not required leave the selection as None.
Scroll through the choices and press the green button to select.
!!Recording will start as soon as the trigger condition is reached. The bottom line of the LCD .
screen is a visual indicator as logging progresses (each square takes a 20th of the selected
duration to fill in).

Time & Motion
Used to setup and store time measurement from either one digital sensor connected to Input 5:A, or
two connected to Input 5:A and Input 6:B.
Digital switch type sensors e.g. Light Gates, have two states ON (low) or OFF (high).
For EASYSENSE QAdvanced to be able to calculate Speed, Velocity or Acceleration, it needs
information about the dimensions of the interrupt used in an investigation. The choice of interrupt
and its dimensions are preset in EASYSENSE QAdvanced’s memory. See page 18 for the list of
interrupts and the choice of preset dimensions e.g. a single interrupt card can be 30, 40, 50, 95, 100
or 120 mm in length.
Example using Time at A - see page 34 - 40 for further details.
